Optical solitons to the space-time fractional (1+1)-dimensional coupled nonlinear Schrodinger equation

Abstract

This study reveals the dark, bright, mixed dark-bright, singular and mixed singular optical solitons to the space-time fractional (1+1)-dimensional coupled nonlinear Schrodinger equation by using the extended sinh-Gordon equation expansion method. The constraint conditions for the existence of valid solitons are given. Under the choice of suitable values of the parameters and the fractional values of alpha and beta, the 2- and 3-dimensional graphs to some of the reported solutions are plotted.
