Application of newly proposed sub-ODE method to locate chirped optical solitons to Triki–Biswas equation

Abstract

In this article, we first comment on the generalized sub-ODE and its solutions proposed in the article [6]. Secondly, we propose, for the first time, a new method which will be called a new modified sub-ODE method to construct a new chirped soliton solutions to the nonlinear Triki–Biswas equation with non-Kerr dispersion. The results show that these envelope solitons possess a nontrivial phase chirping which varies as a function of the wave intensity. Chirped bright soliton solutions, solitary wave solutions, periodic wave solutions and other solutions of the Triki–Biswas model are derived and the corresponding chirping of those solitons are also presented.
