Exploring the dark and singular soliton solutions of Biswas–Arshed model with full nonlinear form

Abstract

In this paper, the optical solitons of two nonlinear forms, namely Kerr type and power law form, of Biswas–Arshed model are studied. To construct optical solitary wave solutions of the aforementioned model, the modified extended tanh expansion method was used successful. As a consequence, many new optical solitons including, dark, singular, dark/singular, and periodic soliton solutions are retrieved and verified through MATHEMATICA.
