Analysis of the propagation of flat-topped beam in nonlinear optical fiber

Abstract

In this paper we study wave propagation type Flat Topped through nonlinear optical fibers using as mathematical tool nonlinear equation schrödinger. In this paper we propose to perform a mathematical expansion of a Flat Topped pulse and express it as a combination of Gaussian functions where it is necessary to solve the dynamic equation numerically using the method of Split Step Fourier.
