Abstract
The intra-channel collision of optical solitons, in presence of non-Hamiltonian perturbations, is studied in this paper by the aid of quasi-particle theory. The perturbations terms that are considered in this paper are nonlinear gain and saturable amplifiers along with filters. The suppression of soliton-soliton interaction, in presence of these perturbation terms, is achieved. The nonlinearities that are considered in this paper are Kerr, power, parabolic and dual-power laws. The numerical simulations support the quasi-particle theory.
