摘要
基于多波长光波在双折射光纤中传输的非线性耦合方程，用分步傅立叶变换求耦合方程的数值解，仿真分析了偏振模色散对波分复用系统脉冲波形的影响，并进一步仿真分析了输入功率、啁啾系数、占空比不同时，偏振模色散对系统性能的影响。
Based on multi-wavelength nonlinear coupled Schrodinger equation in birefringence fiber, the numerical solution is gotten in terms of split-step Fourier transform. The propagation behaviors of pulse signals are simulated in multi-channel WDM systems with polarization mode dispersion. When including polarization mode dispersion, influences on performance are studied with changing input power, chirp, and signal shape respectively.
