Abstract

In this paper, we have considered a generalized coupled higher-order nonlinear Schrodinger equations. We applied multiple scales method to coupled higher-order nonlinear Schrodinger equations to derive the coupled KdV equation. Then, the extended tanh method is applied to derived coupled KdV equation for exact solutions. The obtained results include solitary wave solutions.
