Optical soliton perturbation with full nonlinearity for Kundu–Eckhaus equation by modified simple equation method

Abstract

This paper secures dark and singular optical soliton solution to the perturbed Kundu-Eckhaus equation where the perturbation terms appear with full nonlinearity. The integration algorithm adopted in this paper is the modified simple equation approach. The solitons appear with certain parameter restrictions that are listed as constraints.
