Solving Generalized Nonlinear Schrödinger Equation by Adomian Decomposition Technique

Gaston Edah, Villévo Adanhoumè & Marc Amour Ayela · Physical Science International Journal · 2021

In this paper, using a suitable change of variable and applying the Adomian decomposition method to the generalized nonlinear Schr¨odinger equation, we obtain the analytical solution, taking into account the parameters such as the self-steepening factor, the second-order dispersi...

A Numerical Method for Pulse Propagation in Nonlinear Dispersive Optical Media

Gaston Edah, Aurélien Goudjo, Jamal Adetola & Marc Amour Ayela · Physical Science International Journal · 2021

In this work, the pulse propagation in a nonlinear dispersive optical medium is numerically investigated. The finite difference time-domain scheme of third order and periodic boundary conditions are used to solve generalized nonlinear Schr¨odinger equation governing the propagati...

Dynamics of the Optical Pulse in a Nonlinear Medium: Approach of Moment Method Coupled with the Fourth Order Runge-Kutta Method

Fessomon Koki, Gaston Edah, Minadohona Maxime Capo- Chichi, Gaetan Finagnon Djossou ´, Camille Elloh & Marc Ayela · Physical Science International Journal · 2020

In this paper, we considered the nonlinear Schrodinger equation and applied the moment method ¨ in order to investigate the evolution of pulse parameters in nonlinear medium. This mathematical model described the effects of cubic nonlinear and the nonlinear dispersion terms on th...

Analytical Solutions to Generalized Nonlinear Schrödinger Equation by Adomian Decomposition Technique

Villévo Adanhounme, Gaston Edah & Norbert M. Hounkonnou · Advances in Research · 2019

We study the higher-order nonlinear Schrödinger equation which takes care of the second as well as third order dispersion effects, cubic and quintic self phase modulations, self steepening and nonlinear dispersion effects. Taking advantage of the initial condition, we transform t...
