摘　　要：本文考虑了光子密度、增益谱色散、放大自发辐射噪声(ASE)、端面反射率和载流子浓度对折射率的影响,并采用细化分段法及四阶龙格-库塔法求解速率方程及光场传输方程,分析了不同端面反射率时单端反射半导体光放大器(RSOA)的动态特性。结果表明端面反射率的适当增加,可以使增益得到提高,增益恢复时间减少,ASE输出功率增加,消光比下降。理论分析为优化RSOA的动态特性具有一定的指导意义。The influence of refractive index cuased by photon density,gain spectrum dispersion,amplified spontaneous emission noise（ ASE）,facet reflectivity and carrier concentration is discussed,and the rate equations and light-field transfer equations are solved by the refined sectionalization and Runge-Kutta method.Meanwhile the dynamic characteristics of different facet reflectivity coefficients of RSOA are also analyzed.Results show that a proper increase of facet reflectivity could raise the gain of SOA and ASE output power,decrease the gain recovery time and extinction ratio.This theoretical analysis could serve as a reference for the optimization of RSOA dynamic characteristics.
