| 摘 要： | 本文就群速度色散对非线性光纤环镜型ＯＴＤＭ解复用器的影响进行了理论与数值分析．首先给出了描述群速度色散与非线性效应之间相互作用的耦合非线性薛定谔方程组，然后用分步傅立叶方法对该方程组进行了数值求解．经分析指出，要达到一定的开关性能，孤子阶数、色散的正负、脉冲宽度及控制和信号脉冲之间的走离时间应满足一定的条件．

| Abstract: | The effects of group velocity dispersion(GVD) on nonlinear optical loop mirror (NOLM) OTDM demultiplexer are analyzed theoretically and numerically in this paper.First the nonlinear Schrodinger equations which describe the interplay of GVD and nonlinearity are given.Then the split step Fourier method is used to solve the equations.The numerical results reveal that the soliton number,the dispersion sign,the width of pulses and the walk off time between the control and signal pulses must satisfy certain values to maintain the performance of the demultiplexer. |
