摘　　要：5G网络的运营,对光模块的功能和性能提出了更高的要求。本文基于光纤中的SRS效应和FWM效应,对基于FWM效应的参量放大器的增益性能做出改进,用龙格-库塔法数值模拟了SRS效应对光纤参量放大器增益性能的影响。分析得到:考虑SRS效应时,信号光增益谱更加平坦,最大增益可达44 dB,增益带宽达到了67 nm。The operation of 5G network puts forward higher requirements for the function and performance of optical module.Based on the SRS effect and FWM effect in optical fiber,the gain performance of parametric amplifier based on FWM effect is improved.The influence of SRS effect on the gain performance of optical parametric amplifier is simulated by Runge-Kutta method.The results show that when SRS effect is taken into account,the signal gain spectrum is more flat,with the maximum gain up to 44 dB and the gain bandwidth up to 67 nm.
