摘　　要：本文研究色散管理孤子在双折射光纤中的传输特性·应用变分法分析并给出了双折射光纤中色散管理孤子参量演化的常微分方程·数值分析双折射对孤子参量的影响,分析发现在双折射光纤中色散管理孤子的宽度和啁啾不再是严格周期性变化·在色散管理的同时进行周期性偏振补偿可以消除走离效应,可以产生管理孤子·Propagation of dispersion-managed soliton in birefringent optical fibers is considered. A set of ordinary differential equations is obtained by means of approximate variational method. Effects of the birefringence on parameters of the dispersion-managed soliton are analysed numerically. It is found that evolutions of pulse duration and frequency chirp are not periodical due to effects of walk-off. When the walk-off is compensated through rotating the axis of the birefringent by 7/2 in the dispersion line, managed soliton can be obtained.
