InstrumentatIon news sprIng 2015

Welcome to the new and expanded Instrumentation News! Starting this issue, we are expanding our reach beyond WaveShaper and WaveAnalyzer news to cover other Finisar products for the R&D and Laboratory markets. These include Finisar's range of high-speed photodetectors and photoreceivers with bandwidths up to 100 GHz, high performance EDFA and Raman amplifiers and diffraction gratings from our new com-pany, LightSmyth Technologies.

WaveShaper 1000/Sp: NoW alSo available for 1µm At Photonics West, Finisar introduced the first WaveShaper operating outside of the 1.55 µm window. This new version of the WaveShaper 1000/SP has been completely redesigned and optimized for use at 1 µm and provides polarization-maintaining pro-grammable filtering with full control of the amplitude and phase spectra. Covering a spectral window of over 50 nm with a cen-ter wavelength around 1040 nm, this new WaveShaper is optimized for Ytterbium-doped fiber lasers in a Master Oscillator Power Amplifier (MOPA) configuration (see Figure.) The 1 µm WaveShaper 1000S/SP is available for sampling. Please contact Finisar at [email protected] if you would like to test a unit.

WaveShaper 16000: Upgrade to dyNamic port coNfigUratioN The WaveShaper 16000S capabilities have been further extended to support additional port configurations. In addition to the standard 4x16 configuration, this instrument now supports 1x19, 8x12 and 10x10 port configurations. User-defined filter functions with arbitrary shape in amplitude and phase

can still be applied between any input and any output port. This flexible port allocation is of particular importance in research of Software Defined Networks (SDN).

Please contact us at [email protected] for more information or to upgrade your existing 4 x 16 port WaveShaper 16000S to dynamic port configuration.

This new dynamic port configurability will be demonstrated at OFC and will start shipping in April.

WaveaNalyzer 1500S high reSolUtioN optical SpectrUm aNalyzer

Finisar is releasing version 1.5 of the Graphical User Interface WaveAnalyzer package. This package provides enhanced signal analysis capability to support Optical Signal to Noise Ratio (OSNR) Measurements with real time update rates of up to 10 Hz. The WaveAnalyzer’s special 6-point OSNR measurement technique supports OSNR mea-surements on densely spaced channels by exploiting the high 150 MHz spectral resolution capability of the instrument.

The new package also includes a wavelength meter mode which takes advantage of the WaveAnalyzer's 150 MHz spectral resolution and outstanding fre-quency accuracy to automatically measure frequency and power of up to 99 channels across the spectrum.

The WaveAnalyzer version 1.5, which incorporates these enhancements, will be available for download starting in April.

Finisar's portfolio of high-speed detectors, receivers and accessories


We are pleased to announce our latest high-power photodetector, the HPDV2120R, for applica-tions requiring high power handling and linearity.

The compact module is based on an advanced waveguide photodetector chip integrated with Bias-Tee. It utilizes a mode-converting tapered waveguide for efficient fiber-to-chip coupling and a 1×4 Multi-Mode Interference (MMI) Coupler. The optical signal is split by the MMI coupler into 4 equal parts and then it’s fed into an array of 4 photodiodes which are connected in parallel.

The advanced performance of HPDV2120R fea-tures a RF-output power of 6 dBm @ 20 GHz and 3

dBm @ 50 GHz, and a high linearity (OIP3) of >20 dBm @ 40 GHz, without external cooling.

The HPDV2120R is suitable for applications within the fields of Analog Photonics, RF-over-Fiber, and many more application requesting high-power handling and linearity. For more information, please visit www.finisar.com/products/optical-components/High-Performance-LW-Detectors.

lightSmyth pUlSe-compreSSioN gratiNgS

The most important properties of pulse compression gratings are high diffraction efficiency and low wave front deformation due to multi-pass use requirements for the gratings. LightSmyth's gratings are fabricated by a unique state-of-the-art projection photolithography and reactive ion etch process which avoids the need for replication and ensures that each grating is, effectively, a master with ultra-low scatter.

HPDV2120R High Power, High Linearity Photodetector.


...pUlSe-compreSSioN gratiNgS (coNt)These high fidelity semiconductor fabrication methods enable precise realization of sophisticated proprietary grating designs and provide diffraction efficiency of more than 94% optimized for linear P-polarization. This minimizes optical losses in the system, which is especially critical for high energy lasers.

The combination of optimized design and manufacturing provides:

• Exceptional diffraction efficiency for selected polarization

• Broad passband and low angular sensitivity

• Low wavefront deformation in transmission by using ultra-polished quartz substrates

• High damage threshold since only fused silica and highly robust dielectric materials are used (no polymers or organics).
