Abstract The present paper focuses on the chirped soliton solutions of the Fokas–Lenells equation in the presence of perturbation terms. A complex envelope traveling-wave solution is used to reduce the governing equation to an ordinary differential

We have derived solitary wave solutions of generalized KdV-type equations of fifth order in terms of certain hyperbolic functions and investigated their stability. It has been found that the introduction of more dispersive effects increases the stabi

The objective of the present study is to examine the behaviors of chirped optical solitons in fiber Bragg gratings (BGs) with dispersive reflectivity. The form of nonlinear refractive index represents polynomial law nonlinearity. By virtue of phase-m

In this comment, we show that the exact solution of the RKL model which has been obtained by Triki and Taha (2009) is not true. Then, the exact analytic solutions of the RKL model are derived with constraint conditions.

This paper retrieves optical soliton solutions to the perturbed Fokas–Lenells equation by the application of several forms of mapping methods. The solutions are initially in terms of Jacobi's elliptic function and in the limiting case of the modulu

The present work discusses solitons and other solutions to nonlinear Schrodinger equation in metamaterials with nonlinear influence of non-Kerr law type. The nonlinearity of metamaterials is assumed to be because of anti-cubic law. Some perturbation
