My biography is at the end of this page. Fiber Optical Communications Practical, very high speed networks will be required to support the next generation of information technology applications for business, medical, and industrial needs. Optical links can provide unprecedented communication capacity because of their large, cheap bandwidth. The challenge is to develop practical modulation methods that can use that bandwidth effectively to provide high capacity or to serve many simultaneous users. We have developed a modified version of wavelength division multiplexing that significantly reduces four wave mixing interference and improves performance.
Testbed measurements are underway to verify our calculations.
We have built and tested passive, all-optical encoders and decoders for this system that can operate at arbitary speeds, and are currently developing an integrated photonic waveguide circuit to perform these functions. My group has been engaged in a comprehensive program of research directed towards improved understanding of the physics of vacuum ultraviolet sources, the application of that knowledge to improve source practicality and accessibility, and the use of those sources for applications. We have applied both incoherent, broad bandwidth, laser-produced plasma sources and coherent sources to microscopic imaging, where short wavelengths can provide improved resolution and contrast with minimum sample preparation.
