Keywords:Supercontinuum Generation, Nonlinear Schrödinger Equation, Self Phase Modulation, Raman Scattering, Self Frequency Shift
In this paper, we have used the general nonlinear Schrödinger equation (GNLSE) to study the spectral evolution of a short light pulse propagating through an optical fiber. The equation includes the main factors affecting its propagation through the fiber, involving the linear and nonlinear dispersive characteristics. We find the asymmetry feature of the spectrum due to the Raman Effect. The first order group velocity dispersion sets in after a finite propagation length. We have systematically studied the evolution of the pulse through a nonlinear medium.
