Bright – dark optical solitons for Schrödinger-Hirota equation with variable coefficients

Abstract

This work is dedicated to exploit Schrödinger-Hirota equation (SHE), which regulate the proliferation of solitons in diverse variety of dispersive optical fibers. More precisely, SHE with variable coefficients are appraised with power law nonlinearity. Bright and dark optical solitons to the considered model are successfully flourished by practicing different ansatz method with time dependent coefficients. Moreover, graphical portray of acquired solutions with free parameters are presented properly for retrieving sustainability of such solitons.
