Novel Scheme of All-optical AND Gate Based on Fabry-Perot Semiconductor Optical Amplifier

摘要

A novel scheme of all-optical AND gate based on a Fabry-Perot semiconductor optical amplifier(FP-SOA) is proposed and its feasibility is verified by simulation. Using this scheme, all-optical AND gate can be realized with the extinction ratio of 10 dB. The influence of pulse interval and pulse width on the extinction ratio is also investigated.
