Generalized (G′/G)-expansion method and exact traveling wave solutions of the perturbed nonlinear Schrodinger's equation with Kerr law nonlinearity in optical fiber materials

In this paper, we investigate the nonlinear the perturbed nonlinear Schrodinger's equation (NLSE) with Kerr law nonlinearity given in Zhang et al. (Appl Math Comput 216: 3064-3072, 2010) and obtain new exact traveling solutions by using generalized (G'/G) expansion method. Under some parameter conditions, some explicit expressions of solutions for the equation are obtained. These solutions contain hyperbolic function solutions, trigonometric function solutions and rational function solution.
