Problems Associated with the Propagation of Solitons in Fibres

Abstract

The modern-day technique of optical solitons seems to hold immense promise for transmitting digital data at exceedingly high rates, with potential performance levels that go beyond those achievable with traditional linear systems. The focus of the present study, as detailed in this paper, pertains to the examination of soliton pulse propagation. Specifically, An optimal balance between self-phase modulating (SPM) with the group velocity dispersal (GVD) has been found through the use of the nonlinear Schro equation (NLSE) with the Fourier transform split-step method (SSF) in numerical resolution., as represented by SPM + GVD = 0. This equilibrium serves to generate a soliton wave that propagates through an optical fiber without undergoing any deformation, thereby preserving its shape and velocity during propagation. The accuracy of this assertion was substantiated through the COMSIS simulation of soliton propagation for two cases, namely, the fundamental and higher-order ones.
