| 摘 要： | 为了准确描述受激喇曼散射效应(SRS)对波分复用石英光纤通信系统的影响,基于石英光纤喇曼增益谱可以拟合为直线的特点,给出不等线性衰减系数时的N-波道前向稳态SRS耦合方程的形式解,并分情况对该形式解进行讨论,得出一些特解。所得结果能很好地验证关于等线性衰减系数时的已有研究,并为光纤喇曼放大器的设计及运用数值方法研究波分复用石英光纤通信系统中的SRS效应提供参考。

| Abstract: | In order to more accurately describe the effect of the stimulated Raman scattering(SRS) to wavelength division multiplexing(WDM) optical fiber communication systems,assuming that the Raman gain profile of silica is a liner function,it gives form solutions of N-channel SRS steady-state couple wave equation of different attenuation coefficient.Then some special cases about the form solutions is discussed,some particular solutions are obtained.The particular solutions well verified the previous studies and provided the theoretical basis for designing Raman Fiber Amplifier(RFA) and studying the SRS in single-mode silica fiber in WDM optical communication system using the method of numerical analysis. |
