Nonlinear optical fiber: transmission medium of ultrashort chirped pulses

Abstract

Generation of fundamental soliton in nonlinear optical fiber from chirped pulses of different initial shapes will be discussed. Results of numerical calculations having in view solution of Nonlinear Schrodinger Equation for complex initial condition using Split-Step Fourier Method will be presented. Initial shape-dependent critical value of the chirp parameter will be determined. Critical value is such a value of the chirp parameter at which generation of soliton in optical fiber is impossible.
