Abstract: We demonstrate an optical power limiter using a
semiconductor optical amplifier (SOA)-based interferometric gate
powered by a strong continuous-wave input signal. We present a
detailed theoretical and experimental investigation of the power
limiting characteristics of saturated SOA-based switches, showing
good agreement between theory and experiment.
Abstract: We present experimental and theoretical analysis of an optical hard limiter that uses
SOA-based interferometers. Its operation relies on the deep saturation of SOA and it can suppress
amplitude modulation in excess of 10 dB.
