Femtosecond Pulse Propagation in Optical Fibers under Higher Order Effects: A Moment Method Approach

Fessomon Koki, Gaston Edah, GaEtan Djossou, Ezivi Baloitcha & Minadohona Maxime Capo-Chichi · Current Journal of Applied Science and Technology · 2022

In this paper, we use the moment method approach to investigate the evolution of pulse parameters in nonlinear medium.The pulse propagation is modelled by higher order nonlinear Schr¨odinger equation (NLSE). The application of moment method leads to variational equations that are...

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...
