利用两种方法研究了有源放大器波分复用系统光纤链路中交叉相位调制的不稳定性 .首先利用非线性薛定谔耦合方程 ,在小幅度扰动下 ,研究了正常色散和反常色散光纤中的交叉相位调制不稳定性 .由于相位噪声涨落 ,利用分裂步长傅里叶变换法与Monte_Carlo法 ,模拟了有源放大器链路中反常色散和正常色散情况下的调制不稳定性 .两种方法得到的结论基本一致
Two kinds of methods are used to study the instability of cross-phase modulation in optical fiber link of active amplifier WDM system.Firstly, the nonlinear Schrodinger coupling equation is used to study the effects of small amplitude perturbation on normal phase dispersion and anomalous dispersion fiber Cross-phase modulation instability. Due to the fluctuation of phase noise, the split instability Fourier transform and Monte-Carlo method are used to simulate the modulation instabilities in the case of anomalous dispersion and normal dispersion in the active amplifier link. The conclusion is basically the same
