ECOC’01 Technical Programme
ECOC is the premium event on optical communication within Europe with more than 2,000 participants and a largetechnical exhibition. It is an international platform for everyone involved in optical communication, from scientists tomanagers working in the field.More than 300 papers will be presented in parallel sessions covering the most recent technical progress.The role and the impact of photonic technology in present and future telecommunication networks will be explainedand discussed in tutorials, invited papers and short courses.
ECOC’01 will be held in combination with POF’01, the 10th International Conference on Plastic Optical Fibres. POF is amajor event on polymer optical fibres and waveguide technology and provides a forum for discussions on new devel-opments of the technology, the system implementation and practical applications. ECOC’01 will have parallel sessionswith contributed papers (both oral and poster presentations) on the topics listed below, as well as invited papers andtutorials on current topics. During the conference 4 symposia on selected topics will be organised. Prior to theConference, on Sunday 30 September, a number of short courses and workshops will be organised.
ECOC’01 will cover the following fields:
1. Fibres, Cables and Fibre Components– Theory on propagation characteristics– Design and transmission characteristics– New materials, reliability measurement techniques
and test procedures– Splitters, couplers and fibre-based filters– WDM and OTDM components– Nonlinear effects– Special fibres and fibre sensors– Low-loss plastic optical fibres and waveguides– High-bandwidth plastic optical fibres– Fibre Bragg gratings and related devices– Fibre-optic functional/passive devices
2. Optoelectronic and Integrated Optics Devices– Device theory, modelling and simulation– Materials, processing, micro-fabrication– Semiconductor lasers, LEDs and photodetectors– Semiconductor laser amplifiers, modulators and

Short Courses on Sunday
10:00 – 13:00 SC1: Polarization Mode DispersionNicolas Gisin – Geneva University, Switzerland
Single-mode fibers actually support two modes: the two polarization modes. The effects of unavoidable birefringence are,moreover, made more complex by random polarization mode coupling. The use of statistical tools is thus necessary toanalyse PMD. Despite very significant progress over the last years, PMD remains a central issue both for measurementspecialists and for system engineers. The course will introduce the basic concepts, measurement schemes and discuss theimpacts on transmission systems. Second-order PMD, Polarization Dependent Loss, Polarization OTDRs, Polarizationcontrollers and means to compensate for PMD will also be considered.Nicolas Gisin, head of the optics group at Geneva University, made numerous contributions to the field of fiber measure-ment techniques. In particular, he has a long experience with polarization effects in fibers. His group develops various spe-cialized prototypes for the telecom industry. He is also interested in quantum communication, with renowned performancesin experimental demonstrations of quantum cryptography.
10:00 – 13:00 SC2: Optical Internetworking ArchitectureJoseph Berthold – CIENA, USA
Carriers worldwide are just beginning to transition the architectures of their networks to better adapt to the demands ofdata traffic, to better scale capacity in light of an unrelenting increase in traffic demand, and to reduce the fundamentalcosts of capital and operations. The elements of the Optical Internetworking Architecture are high speed, high capacitydata switches, multi-terabit DWDM transmission systems, and optical switches. In contrast to previous carrier networksthe Optical Internetworking Architecture enables distributed control of the network, including the coordinated control ofthe data and optical portions of the network. This is an intermediate level course. It assumes a basic knowledge ofEthernet, IP, ATM, SONET, and DWDM.Course Benefits: This course will provide the audience with an understanding of:
- Problems carriers face in scaling current network architectures- Architecture of optical internetworks in access, regional and long haul applications- Functionality and scale of data switches- Functionality and scale of DWDM transmission systems- Functionality and scale of optical switches and all-optical switches- Control planes for optical internetworks, including work underway in IETF, OIF and ITU-T
Joseph Berthold is Vice President, Network Architecture and Standards at CIENA. There he contributes to the definition of opti-cal networking products, and is responsible for coordination of CIENA’s work in industry standards. He has served as the TechnicalCommittee Chair of the Optical Internetworking Forum since its formation in 1998. He has been a long-term contributor to OFC,is the General Program Co-chair for OFC 2003, and an IEEE COMSOC representative on the OFC Steering Committee. Formerly, he was an Executive Director in the Applied Research Area of Bellcore, where he was responsible for the man-agement of research programs related to broadband network systems, and was the Program Manager and chairman of theTechnical Management Committee for the Multiwavelength Optical Networking Consortium MONET).
10:00 – 13:00 SC3: WDM Transmission System DesignStan Lumish – JDS Uniphase, USA
Erbium doped fiber amplifiers (EDFA) have created a revolution in the network transport business. EDFA’s offer theextraordinary promise of simultaneous achievement of high gain, high output power of multiple 1550 nm optical channelsindependent of bit rate and format. The practicality of EDFA’s has advanced the capabilities of numerous other technolo-gies, including lasers, passive optical filters, and pump lasers, to name a few. This has led to extensive global deploymentand demand for high bit rate, dense wavelength-division multiplexing (WDM) systems.In practice there are numerous factors that must be taken into account when WDM transmission systems are designed. Inaddition to the benefits of WDM transmission systems there are problems: with amplification, comes noise addition, withhigh output powers, comes optical non-linearities, with high bit rates and long distances, come dispersion limitations.Issues from component specification to network design need to be addressed to best take full advantage of the capabilitiesof dense WDM transmission systems.This basic-level course will review the basic requirements and issues around laser transmitters, receivers, optical filtersand EDFA’s for implementation in WDM transmission systems. The issues of impairments, noise, non-linearities and dis-persion, and different fiber types will be discussed. The implications of upgrading a system from 2.5 Gb/s to 10 Gb/s willbe used as an illustration for all of the principles described above.Stan Lumish received the B.E., M.S., and Ph.D. degrees from the State Univ. of New York at Stony Brook. He joined AT&TBell Labs in 1982 as a member of the technical staff. He has worked on optical technologies for terrestrial lightwave systemsoperating at 400 Mb/s and 1.7 Gbit/s. In 1988, he became Technical Manager for the development of high speed optical inter-faces and optically amplified dense WDM systems. For ten years, Stan led the optical technologies activities forAT&T/Lucent terrestrial lightwave systems, including capacities from 2.5 Gb/s single channel to 400 Gbit/s multichannel sys-tems. In 1994, he was awarded the AT&T Bell Laboratories Fellow award for “innovation and leadership in the introductionof third generation lightwave technology, especially optical amplifiers and dense wavelength multiplexing in the AT&T andother terrestrial networks” In 1999, he was promoted to the position of Director of SDH R&D Advanced Technologies. In2000, Stan joined JDS Uniphase to become a Vice President and create an Optical Networks Research activity.
10:00 – 13:00 SC4: Tunable Lasers: Technologies and ControlJens Buus – Gayton Photonics Ltd, UK
This course will describe the state of the art of optical sources for DWDM systems, with emphasis on tunable lasers, tun-able laser technologies, and control of tunable lasers. The course will include a brief introduction to semiconductor laser basics, and also provide some background on DFBlasers, in particular how a grating works as a wavelength selective element in DFB and DBR lasers. The characteristicsof these lasers will be discussed. Tuning mechanisms and tuning properties will be described, and the operation of modi-fied structures with extended tuning range will be explained, including sampled gratings and super structure gratings. Theproperties of codirectional couplers and the use of these in tunable lasers will be discussed. Devices such as external cav-ity lasers, wavelength selectable lasers, tunable VCSELs, and non-semiconductor alternatives, such as fibre lasers andwaveguide lasers will also be described. Throughout the course numerous examples of laser structures from the recenttechnical literature will be presented. Practical issues such as characterisation, operation and control of tunable lasers,as well as switching speed and reliability, will be included.Jens Buus received the Lic. techn. (PhD) and Dr. techn. (DSc) degrees from the Technical University of Denmark (TUD).Since January 1993 he has been a consultant at Gayton Photonics Ltd. He has worked as project manager in the EuropeanRACE and ACTS programs and is currently project manager for a project under the IST program. He has authored or co-authored about 60 papers, about 60 conference papers and 2 books. During the academic years 1998-1999 and 1999-2000he was a LEOS Distinguished Lecturer. He is a Fellow of the IEEE, and a member of the Optical Society of America, theInstitute of Electrical Engineers and of the Danish Physical Society.
14:00 – 17:00 SC5: Optical Networking Architectures, Standards,Protection and Restoration
Paul Bonenfant – Photuris, USA
A major challenge facing network architects is the appropriate choice of optical network architecture and data network-ing technologies optimized for emerging broadband applications. With innovations like GbE and 10GbE aimed at address-ing a continuing, seemingly insatiable bandwidth demand down to the end-user, new breeds of network architectures, builtwith new classes of network elements, are likely to emerge. This course will outline some of these emergent optical net-work architectures, spanning wide area network (WAN), regional, and metro area network (MAN) applications, includingemerging techniques for mapping “IP over fiber.” Particular focus is placed on the various options for providing protec-tion and restoration at the optical layer – from basic definitions of optical protection and restoration schemes, to theunderlying mechanisms for their implementation. Included will be an update on selected recent developments in Standards fora:
- Recent advances in Generalized MPLS (GMPLS) in the IETF, the Optical UNI in the OIF, and the definition of AutomaticallySwitched Optical Networks (ASON) in ANSI and ITU, in the context of optical layer protection and restoration;
- Framing techniques for mapping IP/data signals over existing and emerging optical transport networks, including butnot limited to: GbE/10GbE and Resilient Packet Rings in the IEEE; Generic Framing Procedure (GFP), VirtualConcatenation (VC), and the Link Capacity Adjustment Scheme (LCAS) for SONET/SDH in ANSI and ITU; and ITUG.709 “Digital Wrapper” Optical Channels.
This intermediate level short course assumes basic knowledge of WDM and Optical Transport Networking, SONET/SDH,IP/MPLS, and Ethernet.Paul BONENFANT ([email protected]) serves as Chief Architect at Photuris, Inc. His experience spans SONET/SDH,WDM, and Optical Networking transport architecture, product evolution planning, network survivability, and associated globalstandards development. Before joining Photuris, Paul served as a business development manager for Mergers and Acquisitionsin Lucent’s Optical Networking Group, and led a group responsible for optical network architecture evolution. Prior to joiningLucent, he led requirements and standards development for SONET/SDH self-healing rings and dense WDM systems at BellCommunications Research (Bellcore, now Telcordia). Paul holds a BS degree in Engineering and Applied Science, and an MSdegree in Electrical Engineering, both from the California Institute of Technology in Pasadena, California.
14:00 – 17:00 SC6: Combating Degrading Effects in Non-Static andReconfigurable WDM Systems and Networks
Alan Eli Willner – University of Southern California, USA
As point-to-point links become more sophisticated, single-channel and WDM systems must dynamically adapt to chang-ing environmental and traffic conditions in order to avoid SNR degradation. This scenario erupts into a much greater chal-lenge when channels originate at different locations, as is the case with add/drop multiplexers, reconfigurable cross-con-nects, circuit-switched networking, and, eventually, optical packet switching.This short course is intended for people interested in non-static and reconfigurable WDM systems and networks. We will iden-tify dynamic channel-degrading effects and examine possible practical solutions. We will discuss changes in time- and wave-length-multiplexed systems that are generated from various optical technologies and that occur on time scales ranging fromminutes to less than nanoseconds. Some topics to be highlighted include: management of fiber-based chromatic dispersion andnonlinear effects, non-uniform EDFA gain, physical network topologies, switching-related power transients, WDM channelpower equalization, intra-channel crosstalk, wavelength drifts, polarization mode dispersion, and network wavelength routing.Alan Willner received his Ph.D. from Columbia, has worked at AT&T Bell Labs and Bellcore, and is Professor of ElectricalEngineering at USC. He has received the following awards: NSF Presidential Faculty Fellows Award from the White House,Packard Foundation Fellowship, NSF National Young Investigator Award, OSA Fellow, Fulbright Foundation Senior ScholarsAward, Semiconductor Research Corporation Fellow, USC Best Engineering Teacher Award, and Armstrong FoundationMemorial Prize. His professional activities include: LEOS V.P. for Technical Affairs, Chair-Elect of the OSA TechnicalCouncil, Elected Member of the LEOS Board of Governors, CLEO Program Co-Chair, LEOS Annual Meeting ProgramChair, OSA Annual Meeting Program Co-Chair, OSA Photonics Division Chair, OSA Optical Amplifier Program Co-Chair,IEEE/OSA JLT Editor-in-Chief, IEEE JSTQE Editor-in-Chief, and OFC Steering and Program Committee Member.
14:00 – 17:00 SC7: Optical Micromachines in the Evolving OpticalNetwork
Randy Giles – Lucent Technologies, USA
New capabilities brought about by key developments in micromachine technology will facilitate growth of the core net-work that supports the Internet. Large-scale photonic crossconnects using optical micromachines will improve the effi-ciency and lower the cost of optical networks. Other photonic switch solutions using micromachines include flexible opti-cal add/drop multiplexers and medium-sized selector switches. Terabit-capacity line systems requiring stringent monitor-ing and control of DWDM channels may also benefit from newly-developed attenuators and micromechanical spectralequalizers. This short course will describe trends in optical networks, identify applications of micromechanical devices inphotonic subsystems, summarize basic micro-electromechanical principles and discuss several examples of microme-chanical devices. Randy Giles is director of the photonic subsystem research department at Lucent Technologies. His current responsibili-ties include the design and demonstration of MEMS-based optical crossconnects, add/drop multiplexers, spectral equal-izers, and switches. In his 14 year career at Bell Laboratories, Dr. Giles pioneered the modeling and use of erbium-doped fiber amplifiers for lightwave systems, demonstrated the first optical add/drop multiplexers by means of Bragg-grating technology and most recently has been developing optical network applications of micromachines. Dr. Giles is agraduate of the universities of Alberta and Victoria in the study of intense laser-plasma interactions. Before BellLaboratories, Dr. Giles worked at Nortel’s research labs on their first gigabit optical transmission systems. He is a fellowof the Optical Society of America and recipient of the 2000 Discover Award in Communications.
Participation to these workshops is free, but registration is required. Attendance is limited.

14.50-15.30 The Attractive Start-Up: the Global Player’s PerspectiveWinfried Horsthuis, Independent advisor, Manotick TechnologyOne of the common scenarios in the evolution of a start-up business is to beacquired by another company. Although this outcome is not usually the inten-tion at the founding phase, it is definitely a possibility, which needs to belooked at during the founding and early company stages. Both from a fund-ing and a valuation perspective it is a key attribute to be ‘highly wanted’ byestablished companies, hence it is important to understand what characteris-tics make a start-up interesting in the eyes of large corporate acquirers. It isalso highly relevant to understand the current business environment, sincewhat is good in today’s market may not be ideal under different market con-ditions. The presentation is focused on finding answers to these questionsthrough real world examples as well as through the use of analytical methodsto help understand the photonics industry play grounds.Winfried Horsthuis obtained a Ph.D. in Engineering from Twente University, theNetherlands, in 1987. He joined Akzo Nobel Research to participate in researchon materials and applications for the Information Technology sector. In 1993,Winfried was appointed General Manager of a newly established Business Unitto commercialize the company’s polymer waveguide technology. In 1996 hejoined JDS Fitel as Vice President Strategy and Business Development. After thecompany executed a large number of strategic acquisitions and mergers (vary-ing from start-ups to large corporations), Winfried changed gears again and wentback into the daily business operations. His last assignment in JDS Uniphasewas Vice President Waveguide Products, with responsibility for all of the com-pany’s passive waveguide businesses. In June 2001 he resigned to establish him-self as an independent advisor, located in Manotick, Ontario.

16.00-16.20 How to Navigate a Start Up through the Current EconomicClimate – A Practical Guide to Do’s and Don’ts
Stuart Barnes, IlotronWith the dust settling after the recent collapse of interest in the Telcoms sector“Business as Usual” signs will be hung outside the institutions that have sur-vived. I say “Business as Usual” as this has been perhaps the 5th correctionthat I have experienced in my 22 years in the industry and I confidently pre-dict that there is strong future in the industry just like on the other 4 occasions.But life in companies big and small has changed and although there will beundoubtedly significant growth in the years ahead it is unlikely that the finan-
cial institutions will countenance the heady bubble economy of last yearsTelcoms Sector in the foreseeable future. In this talk I will share with you myexperiences of the roller coaster ride of a lifetime and provide tips as to howto manage in the today’s environment. In particular Do’s and Don’ts with VC’s,Academia, Non Executives, Advisors, The Legal Profession and the rest of theparaphernalia that come with life in Start Up’s.Stuart Barnes received a Doctorate in Engineering from London University.After that he joined STL (now Nortel Research Laboratories) in Harlow, UKworking on optical fibre and cable components. After nearly a decade hebecame Technical Manager of STC, Newport, where he was responsible fordeveloping a new range of terrestrial fibre and cable products. After 2 yearshe moved on to STC Submarine Systems, rising to the position of TechnicalDirector. Following the acquisition of STC Submarine Systems by Alcatel hemoved to Paris to become Deputy Technical Director of Alcatel’s OpticalResearch activities. In March 2000 he returned to the UK to becomeEngineering Director of Ilotron. He is Visiting Professor of ElectricalEngineering at Southampton University.

17.20-18.00 Panel Discussion
International Workshop “Photonic Metro and Access Networks”Organised by the IST OPTIMIST project
SUNDAY 30 Sep 200114:00 – 18:00
Scope of the WorkshopFollowing in the footsteps of the successes achieved in optical core networks,fibre optic technologies are now conquering the domain of metropolitan net-works, and are subsequently expected to penetrate vastly in access networks.Customers demand a wide variety of services (SDH, ATM, FR, Ethernet, …),of capacities, and of Quality-of-Service levels. Well-managed multiple accesscontrol mechanisms, dynamic network configuration and capacity provision-ing at different granularities provide this flexibility, pushing intelligence tothe veins and capillaries of the network. Driven by exploding data trafficdemands, powerful optical packet switching and routing techniques areemerging, built on reduced network layer stacks (e.g., IP-over-WDM).Standardisation and the symbiosis with other first-mile techniques (such aswireless) in access are receiving due attention. At the same time, cost-effec-tiveness remains an important hurdle to be taken.This workshop addresses a range of metro and access solutions found so far,and novel approaches to resolve the still outstanding issues.
14:00 – 14:15 Welcome and IntroductionTon Koonen, Eindhoven University of Technology, COBRA Institute, TheNetherlands
Session 1: Metro Networks14:15 – 14:45 Metro Networks: US Experiences and TrendsPierre A. Humblet, Astral Point Communications Inc., Chelmsford, MA, USAMetro and Access networks are widely seen as the “new frontier” of optical net-works, but predictions about their imminent wide scale deployment have beenslow to materialize and take changing forms as the years pass. The talk will tryto make sense of what has happened in the US in the last few years. We willexplain what issues were addressed and what technical approaches were taken,describe the changing regulatory environment, the nature of the traffic demandand the economic and technological constraints and goals of the main actors. Wewill also contrast the current leading contenders for the near future, data overTDM and forms of Gigabit Ethernet, and characterize what might come next.
14:45 – 15:15 IST DAVID project: “Access Control Protocols forInterconnected WDM Rings in the DAVID Metro Network”Fabio Neri, Dipartimento di Elettronica, Politecnico di Torino, ItalyDAVID (Data and Voice Integration Over D-WDM) considers a hierarchicalnetwork consisting of several metropolitan area networks (MAN) interconnect-ed by a wide area backbone for the transport of IP traffic. The MAN consists ofoptical packet rings interconnected through a Hub, which also provides theinterconnection between the MAN and the DAVID wide area backbone. We onlyfocus on the MAN portion of DAVID in this presentation. Each node of MANrings has access to a number of WDM channels, which transport optical pack-ets having a fixed duration in time (equal to the so-called time-slot). A multi-slot (a slot in each channel) is available to each node in each time-slot. MANnodes are subject to contentions and collisions, which are avoided by anextended empty-slot access algorithm. The Hub behaves purely as a non-block-ing space switch, routing an entire input multi-slot, arriving from ring X, to anoutput multi-slot on ring Y. The input/output permutation at the Hub can be ingeneral changed in each time-slot. The presentation will focus on accessschemes, fairness control algorithms, and scheduling algorithms to computethe sequence of permutations at the Hub. Simulation results will be presentedto assess the performance of the proposed protocols.
15:15 – 15:45 The IST METEOR Project, a Terabit Optical RingJens Buus, Gayton Photonics, UKThe main objective of METEOR is to design, develop and demonstrate a terabitoptical metropolitan area network with 40 channel capacity and 40Gbit/s perchannel. The optical network will demonstrate the concept of service trans-parency in optical networks, enabling transport of various types of services,while not requiring a truly optically transparent network. Within the project itis planned to realise a complete optical network system, incorporating all therequired functionalities such as management at the optical layer, performancemanagement and quality of signal support, protection schemes, etc. Operationswill be tested in an operator’s installed G.652 standard field fibre environment.In this presentation we will describe the network concept and the node design.In particular we will describe the work on compact OADMs, which is based ona wavelength grouping concept, and on 40Gbit/s components.
15.45 - 16.15 Coffee Break
Session 2: Access Networks16.15 – 16:45 Optical Access Network using FSAN BPON TechnologyHiromi Ueda, NTT, JapanWe describe BPON (Broadband Passive Optical Network) history in NTT, inwhich the field trials using our proprietary BPON systems are shown. The FSANBPON technology is described that we worked to standardize with related oper-ators and vendors in FSAN. BPON system configuration is described based onthe FSAN standard and Common Technical Specification (CTS) that has beenproduced by NTT, BellSouth, France Telecom, British Telecom and SBC. CTSand its objectives and features are also overviewed. The deployment status ofthis system in NTT is described. Current NTT commercial services using the sys-tem is described. Furthermore, we show the system based on the DBA mecha-nism that has been studied in FSAN and services using this mechanism.
16.45 – 17:15 EURESCOM Project P1015 (FREEHANDS): “FSANPON and Wireless Systems Integration for Broadband Access Networks” Marco Spini, Antonio Ascolese, TILab, ItalyThe increasing demand for broadband services, along with the competitiveadvantage that the rapid provisioning of these services could offer, highlightsthe market potential of broadband solutions, both wireless and based onfibers. The flexibility of a multi-technology platform allows to get the advan-tages of both technologies reducing the limiting factors. Integration aspects,OAM capabilities and Service Layer Agreement related to integration ofFSAN (Full Services Access Network) broadband optical access systems withwireless access to provide a full services platform are investigated within theEURESCOM Project P1015 (FREEHANDS).The Project has studied a number of issues related to the service delivery overFSAN and broadband wireless access systems performing several laboratoryand field trial experiments on both platform. This presentation is focused on thepresentation of results obtained on an integrated platform, like for instance:• assessment through field trials of the suitability of interconnection of
FSAN APON and radio systems for high bandwidth applications, meas-urements of ATM parameters under different conditions;
• evaluation of service delivery on integrated access platforms;• OAM capabilities/requirements and Service Level Agreements require-
ments for integrated service platforms.
17.15 – 17:45 IST HARMONICS Project: “WDM/TDM Optical PacketSwitching in Passive Optical Access Networks”Rob Smets, Bell Labs, Lucent Technologies, The NetherlandsA variety of last-mile access technologies, such as digital subscriber line (DSL)and cable modem are being rolled out to connect businesses and residentialusers. Fibre optics has been predicted to become the ultimate solution for high-speed access. The high costs involved have however prevented the introductionin this part of the network. Growing bandwidth demands from new services,and the need to generate revenues from recent investments, increasingly justi-fies the deployment of optical fibre. An optical distribution network is requiredto aggregate and distribute data between metropolitan and wide area networksand local last-mile solutions. In a second stage, this feeder network will con-nect end-users in fibre to the home (FTTH) and building (FTTB) scenarios.In the HARMONICS project (Hybrid Access Reconfigurable Multi-wave-length Optical Networks for IP-based Communication Services), the conceptof a WDM access feeder network, connecting different last-mile networks isstudied. In order to connect a large number of users to the core network, andto allow for flexible allocation of resources (capacity on demand), fast opti-cal packet switching is deployed. Optimal resource utilisation is supported bya medium access control (MAC), which operates on optical packets in boththe wavelength and time domains.Issues that are addressed by the project are services and scenarios forincreasing bandwidth demands and migration. This presentation focuses onthe design of the optical network. Also the management and control of net-work resources will be discussed.

10:15 – 11:00 Mo.M.1.1 Bandwidth Challenges
Stubkjaer K.Research Center COM at the Techn. Univ. of Denmark, Denmark
The fiber optics future is packed with lots of exciting challenges as the demand for bandwidth increases steadily. We havealready reached breathtaking numbers for transmission capacity on an optical fiber, but what will we do when today’s tech-niques and technologies have run out of steam?The shape of the future is a development towards more all-optical signal processing with high-speed capabilities. Theincreasing line rates do also have challenging implications for the switching nodes that must handle huge amounts of traf-fic. We need all-optical functions for packet routing, 3R regeneration, buffering etc. Further into the future we may evenresort to new and advanced ways of handling information such as quantum information and communication techniques.Clearly the bandwidth increase is also dependent on the development of new components using advanced materials andwavelength scale features for precise handling of the photons.Kristian Stubkjaer holds M. Sc. and Ph.D. degrees. After research experience at Tokyo Inst. of Technology, Japan, andIBM T.J. Watson Research Center, USA, he became a faculty member at the Techn. Univ. of Denmark in 1983.

The global and local internet traffic blowout is expected to continue in the next decade fueled by a variety of broadbandservices. The value of the network to the users will be based on the services provided. A new network paradigm based on “single-server-view” for the user-friendly services and “single-router-view” for efficient and quality managed communication isdiscussed. One of the key factors for the realization of this network architecture will be 1000-wavelength photonic tech-nology. Examples of challenges for this technology such as high-resolution tunabilities of source, filter and receivers, aswell as all optical signal processing will be introduced with emphasis from industry point of view.Yukou MOCHIDA received B.S. and Ph.D. degrees in EE from Univ. of Tokyo in 1964 and 1988, respectively. He joinedFujitsu Laboratories in 1964 and worked on various digital transport systems starting from 1.544 Mb/s copper pair sys-tem, 400Mb/s coaxial cable system to the recent 1.76 Tb/s DWDM optical fiber system. From 1965 to 1966 he visitedTechn. Univ. Munich (D).

Mo.M.2.1 Where is the fun in designing 10Tbit/stransmission systems? (Tutorial)Bigo S.Alcatel Research and Innovation, France
As the third millennium begins, terrestrial telecom-munication systems have experienced an unprece-dented thousandfold increase in capacity in just tenyears, thanks to the WDM technique. This evolutionwas made possible by the successive emergence oftechnologies. They involve flat-gain amplification,dispersion compensating fiber and dispersion man-agement, L-band amplification, new fiber types,Raman-assisted erbium amplification, 40Gbit/selectronics, alternative modulation formats, andforward error correction. Laboratory experiments conducted over the yearshave shown how each of these technologies hashelped overcome some of the basic limitations ofpropagation. Based on the example of the mostrecent multi-terabit/s demonstrations, we provideguidelines to break the 10Tbit/s barrier.
Sébastien Bigo was born in Cagnes-sur-Mer,France, in 1970. In 1992, he graduated from theEcole Supérieure d’Optique of Orsay, France. In1993, he joined Alcatel Research and Innovationwhere his main subjects of investigation involvedall-optical techniques for switching, for soliton in-line regeneration, and clock recovery. For thiswork, he received a phD degree from theUniversity of Besançon in 1996. Since 1997, hehas worked on WDM terrestrial systems, with afocus on optical nonlinearities and their impact ofthe optimal fibre characteristics. He led severallarge-scale WDM system demonstrations, yieldingfour transmission records. He now heads theWDM transmission group. He has authored andco-authored more than 60 papers and 20 patents.He is member of IEEE and of the technicalCommittee of LEOS annual meeting.
Mo.F.2.1 Fundamentals and applications ofPHASAR demultiplexers (Invited)Smit M.K.COBRA/DIMES – TU Eindhoven, The NetherlandsPhased-Array Demultiplexers (PHASARs, AWGsor WGRs) are key components in WDM networks.A review will be given of the operation principlesand the performance of PHASAR demultiplexers.These components can be realised in almost anywaveguide technology and are, therefore, verysuitable for integration with other devices.Examples will be discussed of integration withswitches in optical add-drop multiplexers andcrossconnects and with optical amplifiers indevices like wavelength selectors and multiwave-length lasers.

Mo.M.3.1. Automatic Switched Optical Networks:Trends and Standardization (Tutorial)Manzalini A.Telecom Italia Lab, ItalyThe growing trend of data traffic is posing sometechnical challenges for transport networks, notonly in terms of traffic volumes but also related tothe burst and asymmetrical nature of such traffic.As a matter of fact, current TDM networks havebeen designed mainly for voice and leased lineservices, but the transport of data packets on a cir-cuit-switched infrastructure is quite inefficient andas such expensive. So there is the need to migratefrom SDH/SONET-based networks into a moreflexible and dynamic optical infrastructureenabling the transport of larger channels for voice,data and video. In this context, the emerging trendfor Network Operators is reducing investment incircuit networks, increasing investment in high-capacity packet/cell networks where DWDMimplements directly advanced optical networkingfunctionality (ASON – Automatic Switched OpticalNetworks). Currently, a significant effort is madein Standardisation Bodies, such as ITU, to recom-mend ASON. This tutorial paper presents architec-tures and functional requirements of ASON, pro-viding also references about the state-of-art of therelated standardisation process.

Onthe other hand, long-wavelength monomodeVCSELs may be applied in single-mode fiber met-ropolitan area and wide area networks. However,the development of long-wavelength VCSELs inthe 1.3-1.55µm wavelength range had to overcomeconsiderable technological challenges and suc-ceeded only just recently with the realization ofsuitable devices. In this tutorial the basic VCSELprinciples, the essential technological approachesfor long-wavelength devices and the application-relevant laser characteristics are reviewed. Thiscomprises a comparison of the various devicestructures and approaches as well as the presenta-tion of the stationary laser characteristics, the tem-perature dependence, the spectral and beam prop-erties and the dynamic behavior. Finally, I will dis-cuss present research and achievements on high-speed and wavelength-tunable long-wavelengthVCSELs.

Tu.M.3.1. 3R All-Optical Signal Regeneration(Tutorial)Sartorius B.HHI für Nachrichtentechnik Berlin GmbH, GermanyAll-optical networks with photonic switchingnodes based on e.g. “MEMS” are under develop-ment now. Signals will travel over variable kilome-tres of fibre and over unknown number of nodes.All-optical 3R signal regeneration (Re-amplifica-tion, Re-shaping, Re-timing) is required to ensurea high signal quality all over such a net. In this talkthe basic architecture and the function of 3R regen-erators is explained. The needed building blocksare the optical clock recovery that generates astream of synchronised stable optical pulses, andthe decision element with its threshold switchingfunction. Different devices applied for these build-ing blocks will be discussed. The regeneratorsassembled based on these devices have to be eval-uated by loop experiments. These experiments aredescribed and results are given that demonstratethe good system performance of present optical 3Rregenerators. An important and critical issue forfuture flexible networks is operation in asynchro-nous data streams (“IP packet switching”) and atvarious bit rates. A key device towards this appli-cation, an optical clock with an ultra-fast lockingfunction and the potential for bit rate flexible oper-ation, will be presented. At last an outlook will begiven on chances and challenges of optical 3Rregeneration for future transparent networks.
Bernd Sartorius studied Physics in Frankfurt andBerlin. He received his PhD from the TechnicalUniversity of Berlin in 1982. He then joined theHeinrich-Hertz-Institute for Telecommunications,where he first worked on optical techniques for char-acterisation of semiconductors. In 1991 he becamehead of a technological project developing semicon-ductor optical amplifiers. He focussed the projectwork on devices for all-optical signal processing.Novel (patented) types of multi-section lasers andamplifiers were developed and applied especially foroptical clock recovery and optical decision. Severalall-optical 3R signal regenerators were assembledand evaluated in system experiments, partly withpartners at Alcatel in the frame of the EuropeanREPEAT project. Presently Dr. Sartorius is head ofprojects that cover the whole range from design andtechnology of devices up to system experiments onhigh speed all-optical signal processing.

Inaddition, powerful personal computers giving thepossibility to offer new applications pushes thefuture telecommunication network to evolvetowards more capacity and more flexibility to becompatible with the quality of service asked. In thistutorial, we will first describe the different intro-duction scenario envisaged (including the conceptof the IST DAVID project) at the network level,then we will give the functions and the technologyrequired. For each scenario, optical packet switch-ing systems will be illustrated through feasibilityissues. In particular, optical matrices but also opti-cal interfaces will be analysed to make realistic anall-optical concept. Finally we will give somearchitecture/network performance (results from theRNRT ROM project) and draw some conclusionsto really exhibit the potential of optics in this field.

We.M.2.1. Recent Advances in Raman amplifiers(Tutorial)Namiki S.Fitel Photonics Lab, Furukawa Electric Co., Ltd.Japan
Raman amplifier was extensively studied in 70’sthrough 80’s. After the maturation of 1480 nmpump lasers for EDFA in the context of skyrocket-ing demands from Internet, Raman amplifier againcollects lots of attention as a new distributedamplifier, which is completely practical exploitinghigh power output of 14XX nm pumping laserdiodes. This resurgence of Raman amplifier is fur-ther propelled because EDFA based WDM systemsnow face against capacity limit due to lumpednature of EDFA. Also, the signal band of Ramanamplifier can be almost arbitrary by choosing ade-quate pump laser wavelength.In this tutorial, we start with discussions on prin-ciples of Raman amplifier, and then introduce theconcept called ‘WDM pumping’ for pumpingRaman amplifiers to achieve a broad and flat com-posite gain shape. A detailed methodology todesign WDM pumped Raman amplifiers will bedeveloped with several of practical examples. Anumerical modeling for simulation will also be dis-cussed.

We.M.3.1 Advanced Fibre Bragg grating designand technology (Tutorial)Ibsen M.Optoelectronics Research Centre (ORC) atUniversity of Southampton in United KingdomThe technology of Bragg gratings has matured sig-nificantly over the past years, now to the extendwhere significant fibre-optic companies are beingformed with main emphasis based on and aroundBragg grating technology. With the recentadvances in the manufacturing capabilities ofBragg gratings there obviously also will develop ademand for filters of even higher complexity toperform very specific filtering tasks. Currently it isthe imagination that often sets the limits for whatcan be achieved experimentally. A superstructuredBragg grating refers to a Bragg gratings where aslowly varying apodisation-envelope is imposed ontop of the fast underlaying Bragg grating pitch.Such an envelope, performed in real-space, willresult in a specific response in frequency-spaceoften uniquely defined by the superstructure pro-file. In this tutorial we will review the evolution ofBragg grating design and manufacturing techniquesand will show examples of the current state-of-the-art Bragg gratings and application of these in highperformance systems environments. The tutorialwill focus on the requirements to superstructuredBragg gratings in systems and also discuss wherethe practical limitation lay for manufacturability.

We.F.3.1 Ultrafast electroabsorption modulatorswith travelling-wave electrodes (invited)Yamanaka T.NTT Photonics Laboratories, Kanagawa, JapanHigh-speed electroabsorption (EA) modulators arepromising for achieving high-bit-rate transmissionsystems due to their compactness, lower drivingvoltage and integrability with lasers and a pho-todetectors.

We.A.3.3. Optical fiber properties for long-haultransmission (invited)Nelson L.Optical Fiber Solutions, Lucent Technologies, USAIncreasing demand for transmission capacity fordata and internet traffic has motivated impressive40-Gb/s systems demonstrations with over 1bit/s/Hz spectral efficiency. These high-bit-rateWDM systems face a number of challenges includ-ing low tolerance to group-velocity-dispersion andpolarization mode dispersion. The requirement ofmaintaining sufficient optical-signal-to-noise ratiocan be met by utilizing distributed Raman amplifi-cation. In addition, discrete and distributed Ramanamplification can allow S-band transmission aswell as extension of the conventional C- and L-bands. The transmission fiber’s Raman gain effi-ciency and dispersion are important parameters inbroadband, Raman-amplified systems. Futurehigh-bit-rate, high-capacity systems thereforerequire optimized transmission fibers to reach dis-tances of 1000 km or more. We will address a num-ber of these enabling fiber properties, includingdispersion and dispersion slope, Raman gain effi-ciency, and polarization mode dispersion.

Iwill describe the fundamentals on how one canencode information on individual photons in waysto prevent eavesdropping, i.e. for cryptographicapplications, and I will describe the concept ofentangled photons and how that can, and has, beenused for teleportation of quantum states of light. Iwill also discuss what are the needed optical tech-nologies, notably for single-photon generation anddetection. I will discuss and present examples fromthe experimental state-of-the-art, notably fromEuropean IST projects, and will conclude with adiscussion of possible “real world” applications.

Th.A.3.1. Active and passive silica waveguideintegration (invited)Hübner J., Guldberg-Kjær S.COM, Techn. Univ. of Denmark, Lyngby, DenmarkIntegrated optical amplifiers are currently regain-ing interest. Stand-alone single integrated ampli-fiers offer only limited advantage over currenterbium doped fiber amplifiers, whereas arrays ofintegrated amplifiers are very attractive due tominiaturization and the possibility of mass produc-tion. The increasing complexity and functionality ofoptical networks prompts a demand for highly inte-grated optical circuits. On-board optical amplifiers,monolithically integrated with functionalities likeswitching or multiplexing/demultiplexing will allowflexible incorporation of optical integrated circuitsin existing and future networks without affecting thepower budget of the system. Silica on silicon tech-nology offers a unique possibility to selectively dopesections of the integrated circuit with erbium whereamplification is desired. Some techniques foractive/passive integration are briefly reviewed and asilica on silicon based approach is discussed inmore detail. Based on this technology a buildingblock system is proposed, facilitating the design andenabling specific integrated optical circuits.
Th.A.3.2. Miniature erbium doped planar opticalamplifiersPolman A. FOM-Institute AMOLF, Amsterdam, TheNetherlands.Three new erbium-doped planar optical amplifierconcepts are demonstrated: Eu and Yb co-dopingto increase the gain; Si nanocrystals as sensitizersto replace the pump laser by a broad-band lightsource; and electrical pumping in a rare earthdoped electroluminescent polymer.
Th.A.3.3. Box-like filter response by verticallyseries coupled microring resonator filterYanagase Y. et al.Yokohama National Univ., Fac. of Eng., Dept. ofE&C Eng., Yokohama, JapanTriple coupled microring resonator Add/Drop fil-ters with stacked configuration were designed andfabricated.

Social Programme
Sunday 30 September: “Get Together Drink”, RAI Congress Centre (included in registration fee)
Monday 01 October: “Welcome Reception”, Westerkerk, Amsterdam (included in registration fee)
The Westerkerk was officially opened on Whitsunday 1631. It is one of the oldestchurches especially built for the Protestant services, and the largest such church inThe Netherlands. The tower, which occupies a unique place in the affections of the
people of Amsterdam, bears the sym-bol of the imperial crown ofMaximilian of Austria, which was hisgift to the city in gratitude for the sup-port given tot the Austro-Burgundianprinces. It has inspired many songsand poems and remains a symbol ofthe city for Amsterdammers abroad.On October 8th, 1669 the painterRembrandt van Rijn, one of theworld’s most famous painters, wasburied inside the church in a rentalgrave. Nobody knows where. In 1906- three hundred years after Rembrandt’s birth - a plaque was unveiled at one of the pillars in the north aisle, notfar from the place where Rembrandt’s son Titus was buried. Near the church and in view of the tower, Anne Fankwrote her diary in the Annex, her hiding place from the Nazis. Hendrick de Keyser, the city architect, built the church in Dutch Renaissane style, which is characterized by acombination of brick and stone. The church is 29 metres wide, 28 metres high, and has 36 windows.From 1985-1990 the church was completely restored. In the medieval tradition the tower, more than 85 metreshigh, stands projecting from the centre of the west façade. It was completed in 1638. The base of the tower, upto the first gallery, is of brick, while the sections above this is constructed mainly of wood with a facing of sand-stone. The uppermost sections are also of wood, with an outer covering of lead.The hour bell is the heaviest in Amsterdam and weighs more than 7.500 kilograms; its hammer 200 kilograms. The carillon, or set of tuned bells, was cast by François Hemony, who came from Lorraine, and was extensive-ly restored in 1959. It now consists of 50 bells. Every Tuesday from 12 to 1 o’clock the carillon is played.
Wednesday 03 October: “Conference Dinner”, Beurs van Berlage, Amsterdam (separate registration fee)
The Beurs van Berlage is one of the world’s most important architectural monuments. The interior is certainly worth seeing. In addition to the building itself,you’ll find drawings and mock-ups of the building as well as documents about it and the stock trading that took place inside.
