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.
