Time and Frequency Demultiplexing IOC Receivers.

Abstract

The following progress has been made toward the realization of an IOC receiver. (1) GaAs electroabsorption avalanche photodiode (EAP) detectors with responsivities up to 60 A/W have been successfully fabricated in single-mode waveguide structures and evaluated experimentally. (2) The effects of doping, applied voltage, and device dimensions on the performance of EAP waveguide detectors has been evaluated theoretically as an aid to device and system optimization. (3) Using this analysis a three-channel frequency demultiplexing receiver using EAP waveguide detectors has been designed. (4) A three-channel, 1 M bit/sec time demultiplexing system has been designed, constructed, and demonstrated.
