摘要
这是一种用于计算宽带拉曼放大系统传输特性的新方法,综合考虑了色散效应、自相位调制(SPM)、交叉相位调制(XPM)等非线性效应,以及泵浦泵浦、信号信号、泵浦信号之间的受激拉曼散射效应(SRS)和放大的自发辐射噪声(ASE)的影响.作为仿真算法的一个应用,对32×10Gb/s的多波长泵浦的拉曼放大器的四个级联传输系统进行了模拟,比较了不同入射功率对接收性能的影响.
A novel algorithm for calculating transmission performance of broadband Raman amplification system was proposed. In this model the system impact caused by dispersion, self-phase modulation（ SPM）, cross-phase modulation （ CPM）, stimulated Raman scattering of pump-to-pump, taneous emission（ASE） were considered. As an application, signal-to-signal, pump-to-signal and amplified spona 32 × 10Gb/s Raman broadband four-stage system was simulated, and the influence of different input signal power level was compared.
