In this paper, a variable-coefficient nonlinear Schrödinger equation that describes the optical soliton propagation in dispersion management fiber systems is studied. Two- and three-soliton solutions are obtained by using the Hirota bilinear method. Based on those solutions, the effects of related parameters on optical soliton propagation are discussed. By choosing different values of the third-order dispersion, the amplification of optical solitons can be realized. In addition, the interactions among the solitons can be reduced by setting a proper value of the group velocity dispersion. The results of this paper may be helpful to design optical amplifiers or to improve the quality of optical communications.

色散项对有损光纤系统中孤子传播的影响

本文研究了描述色散管理光纤系统中光学孤子传播的变系数非线性Schrödinger方程。通过使用Hirota双线性方法获得了两个和三个孤子解决方案。基于这些解决方案,讨论了相关参数对光孤子传播的影响。通过选择不同的三阶色散值,可以实现光学孤子的放大。另外,可以通过设定适当的群速度色散值来减少孤子之间的相互作用。本文的结果可能有助于设计光放大器或改善光通信的质量。
