有损光纤中的交叉相位调制不稳定性现象

摘要

以耦合非线性薛定谔方程为基础，研究了有损光纤中的交叉相位调制不稳定性现象．结果表明：光纤损耗使交叉相位调制不稳定性增益谱的谱宽和峰值变小，随着传输距离的增加调制不稳定性的增益谱频谱宽度和幅度会逐渐减小．%Based on the extended nonlinear Schr？ dinger equation, the cross phase modulation （XPM） instability phenomenon is studied. The results show that： the cross phase modulation instability gain spectrum width and peak will became small due to the fiber loss, with the increase of the propagation distance modulation instability gain spectrum width and amplitude will reduce gradually.
