Optical dromions for perturbed nonlinear Schrödinger equation with cubic quintic septic media

Abstract

In this paper, we obtain optical solitons and other solitary wave solutions for (2+1)-dimensional nonlinear Schrödinger equation (NLSE) with the aid of extended modified auxiliary equation mapping method, together with cubic-quintic-septic nonlinearity. We obtain bright, dark, singular, rational, periodic and many other solitary wave solutions for our governing model with constraint conditions.
