Dispersive optical solitons of time-fractional SchrOdinger-Hirota equation in nonlinear optical fibers

In this article dispersive optical soliton solutions that are governed by the time fractional Schrficlinger-Hirota equation have been presented. Some new soliton solutions of the time-fractional SH equations are obtained in this work. Using extended auxiliary equation method, optical soliton solutions are sought for the fractional SH equations with power law nonlinearity as well as Kerr law nonlinearity. Using fractional complex transform the time-fractional SH equation is converted into the nonlinear ordinary differential equation, and then, the resulting equation is solved using a novel analytical method viz. extended auxiliary equation method. As a result of this, some new optical soliton solutions have been successfully obtained. The obtained results show that the proposed method is a straightforward technique to find out new optical solutions of time-fractional SH equation. (C) 2019 Elsevier B.V. All rights reserved.
