Paper Abstract

Silicon photodiodes with active area dimensions of 1-mm and 5- mm lengths and approximately 30-micrometers width fabricated by a standard, 2-micrometer complimentary metal-oxide-silicon process have been used in a coherent optical processing system with ac coupling. The effective bandwidth of the detectors as measured in the coherent optical test arrangement was greater than 1.25 GHz, and it is estimated that the actual bandwidth of the detectors as used in such a system may be 5 GHz, where ac coupling removes the effects of the full widths at half maximum and of the fall times of the detectors on the test arrangement response. Photodetector rise times in response to impulse optical excitation at 810-nm wavelength were of the order of 100 ps.
