ACCURATE NUMERICAL SIMULATION OF HIGHER ORDER SOLITON DECOMPOSITION IN PRESENCE OF TOD AND SELF- STEEPENING

Generally, one considers only the groupvelocity dispersion (GVD) and self-phase modulation (SPM) induced solitons inoptical communication while other higher order effects such as the third-orderdispersion (TOD), self-steepening, and stimulated Raman scattering are wellthought-out only perturbatively . In this article, we study the existence ofthe TOD and self-steepening induced soliton solutions. The results haveshown that, the combination of the linear with nonlinear effects escort to newqualitative feature as a shifting and the center-shift beside the deformationin the shape of the soliton. To accomplish this purpose we used, the split-stepFourier Method, in our simulations, that is broadly used to simulate numerical solutionsof the nonlinear Schrodinger equation.
