Exact solutions of the time fractional perturbed nonlinear Schrödinger equation in optical fiber materials by modified exp-function method.

In the present study, the modified exp-function method has been utilized for finding the exact solutions of the time fractional perturbed nonlinear Schrödinger's equation with Kerr law nonlinearity and the obtained solutions are studied via their graphical representations. The changes that occur in the behaviour of the exact solution with the changes in the fractional derivative parameter are well demonstrated. 3-D graphs of the obtained solutions are plotted and there their physical interpretation has been provided in this study.
