Interaction of optical fiber solitons in the distributed PT-symmetric nonlinear couplers

Abstract

Abstract: In order to discuss the stability and interaction of optical fiber solitons in the application device, two linearly coupled nonlinear Schr?dinger (NLS) equations with variable coefficients were investigated numerically. And the weak soliton interaction in the PT-symmetric nonlinear coupler with periodically distributed dispersion and nonlinearity is presented, under the different initial conditions, including the case of in-phase injection of two or three solitons with equal amplitudes, and the case of in-antiphase injection of two solitons in three solitons. Also, the stability of the weak soliton interaction with respect to the finite initial perturbations was discussed. The results show that the finite initial perturbations could not influence the main character of the weak soliton interaction.
