本文综合考虑了在非线性效应和色散效应作用下,横向分段连续介质中孤立波的传播。并以椭圆芯单模阶跃光纤为特例,讨论了光纤结构参数、孤立波振幅对偏振色散和孤立波宽度的影响。理论结果表明,在特殊的孤立波振幅下,偏振色散为零。

Propagation, properties of solitons in a transverse segmentally continuous medium (for example, an elliptical-core single-mode step-index fiber) are analysed by considering both the nonlinear effect and dispersion effect. Fiber configurations and effects of the soliton amplitude on polarization dispersion and soliton wave-width are discussed. Theoretical calculations show that the polarization dispersion reaches zero at a specific amplitude of the soliton.
