The Bright Soliton Solutions of Two Variable-Coefficient Coupled Nonlinear Schrodinger Equations in Optical Fibers

摘要

In this paper, with the aid of symbolic computation the bright soliton solutions of two variablecoefficient coupled nonlinear Schrodinger equations are obtained by Hirota's method. Some figures are plotted to illustrate the properties of the obtained solutions. The properties are meaningful for the investigation on the stability of soliton propagation in the optical soliton communications.
