Dr. Andrew M. Weiner is the Scifres Distinguished Professor of Electrical andComputer Engineering at Purdue University. He earned his S.B., S.M., and Sc.D. fromMassachusetts Institute of Technology. Dr. Weiner received the Purdue UniversityHerbert Newby McCoy Award, the IEEE Photonics Society Quantum ElectronicsAward, a National Security Science and Engineering Faculty Fellowship from the U.S.Department of Defense, and selected into the National Academy of Engineering.

In fiber communication systems, chromatic dispersion causes individual bits tobroaden due to their range of frequencies, which leads to intersymbol interference.While there are dispersion compensation methods currently available, thisinterference leads to a large error rate, especially with higher data rates. With newlightwave channel systems offering higher data rates, methods for programmablecontrol of pulse broadening are needed.

Researchers at Purdue University have developed a method for controlling pulsebroadening due to chromatic dispersion in optical fiber communications andnetworking. This method uses pulse shaping to allow lightwave communicationsystems to run at higher speeds over longer distances and can be applied to bothhigh speed TDM and WDM optical communications. The dispersion compensator canoperate for signals with unspecified polarizations states and can be configured toprovide substantially zero polarization dependent loss.
