摘要/Abstract

摘要：系统地研究了同向抽运光纤拉曼放大器的增益特性，并对分析增益的数值模拟和求解析解2种方法进行了比较.采用龙格库塔法的算法对增益进行数值仿真，分析了所有参量在小信号和大信号时对增益的影响.将数值仿真结果与解析解进行比较，结果发现小信号时两者结果一致，且解析解的方法更简单；大信号时，数值模拟的方法更适合分析光纤拉曼放大器的性能.

Abstract: In order to analyze the gain characteristics of forward-pumped fibre Raman amplifier(FRA),comparison of two analysis methods—— both numeric simulation and analytical method is presented.At first,numeric simulation of the coupling equations of FRA was provided with Runge-Kutta method,and the effects of all parameters on gain of the amplifier were investigated in detail.Then,based on the study before,numeric simulation method was compared with analytical analysis.It is discovered that:they are similar to each other under small signal,and analytical method is simpler;but numeric simulation is more adaptable to apply in characteristics analysis under big signal.
