Soliton–soliton interaction with dual-power law nonlinearity

摘要

The intra-channel collision of optical solitons, with dual-power law nonlinearity, is studied in this paper by the aid of quasi-particle theory. The perturbation terms that are considered in this paper are of Hamiltonian type. The suppression of soliton–soliton interaction, in presence of these perturbation terms, is acheived. The numerical simulations support the quasi-particle theory.
