摘　　要：从考虑偏振模色散的光孤子的非线性薛定谔方程角度出发,用分步傅立叶方法对非线性耦合薛定谔方程进行求解。研究了偏振模色散效应对于光孤子传输系统的影响:首先在单个孤子脉冲的情况下,讨论了光孤子的自俘获效应对于偏振模色散的自适应能力,进而考虑更有意义的脉冲序列的情况,即因PMD引起的两个光孤子之间的相互作用以及能量损失而带来的系统损耗的问题。The paper uses numerical simulations to calculate the Nonlinear Schro＂dinger Equations with the PMD effect. In our simulation, the main investigation is into the transmission properties of the Manakov soliton in optical fibers with PMD. A discussion is given about the self-trapping effect for a single pulse of soliton, which can prevent a soliton pulse with PMD from splitting. Unfortunately, this effect can change when the PMD coefficient becomes larger. Then the pulse sequences is taken into account, which is more significant in real transmission link and a discussion is made about the interaction of two soliton pulses and the loss of soliton energy.
