Theoretical study on non-inverted wavelength conversion based on semiconductor optical amplifier and optical band-pass filter
基于半导体光放大器和光学滤波器的同相波长转换理论研究

A single semiconductor optical amplifier (SOA) assisted by optical filter is exploited to realize high-speed all-optical wavelength conversion,in which,the filter is employed to optimize output spectrum. We propose a spectrum optimizer which contains a band pass filter (BPF) and a delay interferometer (DI). Based on this configuration,80 Gbit/s all-optical non-inverted conversion has been numerically simulated. Furthermore,the quality of output signal has been improved greatly using genetic algorithms to op...
