Soliton-soliton interaction with parabolic law nonlinearity

摘要

The intra-channel collision of optical solitons, with parabolic law non-linearity, 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 achieved. The numerical simulations support the quasi-particle theory.
