Adaptive optoelectronic signal processor with metal-semiconductor-metal photodetector arrays

摘要

Optoelectronic structures utilizing switched fiber delays and switched metal-semiconductor-metal photodetectors for signal processing over a 1.25.GHz bandwidth are presented. Fully tunable finite-impulse-response and infinite-impulse-response structures were synthesized with internal compensation for bias dependency of photodetectors. The application of such filter structures to the equalization of modal dispersion in a multimode fiber is also described. # 1998 Optical Society of America OCIS codes: 250.0250, 120.2440, 040.5160, 160.3900.
