Advances in waveguide photodetectors

W.K. Chan, H. Schumacher, J.B.D. Soole, and A. Yi-Yan,

Many signal processing functions needed for future broadband optical communications and switching networks will be most effectively realized in waveguide-based systems where optoelectronic integrated circuits serve as intelligent control points capable of recognizing and processing the optical signal as required. Fast photo-detectors that can detect light in a waveguide are key to the success of these systems. The year saw significant developments in the integration of photodetectors with both semiconductor and non-semiconductor waveguides.
