光纤中高阶项对光孤子传输的影响

Influence of Higher Order Terms for Propagation of Optical Solitons in a Fiber

本文从修正的高阶非线性薛定谔方程出发,分别讨论了光纤中高阶项,诸如线性高阶色散效应、非线性高阶色散效应和自感应喇曼效应对光孤子传输的影响,并介绍了这些高阶项对光纤孤子传输综合影响的结果和光纤孤子通信的应用前景。

Based on the modified nonlinear schro-dinger equation, we discovered the influence of higher order terms on propagation of optical soliton in a fiber,such as the linear higher order dispersion effect, the nonlinear higher order dispersion effect, the self-induced Raman effect. The resultant influence of all higher order terms described in this paper is given, and the application perspection of optical soliton communicaion is introduced.
