Solitons for perturbed Gerdjikov–Ivanov equation in optical fibers and PCF by extended Kudryashov’s method

Abstract

This paper reveals bright, dark and singular soliton solutions to the perturbed Gerdjikov-Ivanov equation by the aid of extended Kudryashov's method. The nonlinear terms appear with full nonlinearity in order to give a generalized flavor to the model. As a byproduct of this scheme, plane waves and singular periodic solutions fall out and these solutions are listed as well.
