High saturation power and high gain integrated photoreceivers

Abstract

A novel monolithically integrated semiconductor optical amplifier (SOA) receiver is presented. This receiver implements a flared SOA and tapered quantum-well detector. SOAs exhibited 22-dB unsaturated gain and 15.7-dBm output power at the 1-dB gain compression point while the receiver demonstrated 15-GHz bandwidth and -10.5-dBm sensitivity.
