All-optical adders based on transient cross phase modulation using a single semiconductor optical amplifier

摘要

A compact configuration of all-optical adders implemented with a single semiconductor optical amplifier (SOA) and optical bandpass filter (OBF) is presented in this paper. A comprehensive SOA model is put forward to investigate the output performance of all-optical adders. The numerical simulation results demonstrate the influence of these key parameters including input pulse peak power, pulsewidth, repetition rate, and filter characteristics. Moreover some design rules are extracted for the proper selection of these parameters so as to ensure optimum performance. The obtained results confirm the feasibility of our configuration.
