Abstract

We have successfully demonstrated the influence of higher order nonlinear effect (HONE) on soliton interaction. The basic feature higher order nonlinear effects are to shift the soliton pulses temporally such that this shifting helps in avoiding the interaction of in-phase soliton pulses. Here we have concentrated on Third order dispersion (TOD) and intra-pulse Raman scattering (IRS) as these effects are dominant in shifting the pulses comparative to other effects. The phase and temporal shifting characteristics of the soliton is analyzed using the Perturbation theory and Method of Moments theory analytically. Similarly, the Split-Step Fourier transform (SSFT) is used to analyze the effect numerically and we have good approximation between the analytical and numerical studies. Further, finally the influence of these effects on soliton interaction is noted in a single channel telecommunication model and the outputs are characterized by Time domain analyzer (TDA) view and Q-value measurements..
