Influence of the initial parameters on soliton interaction in nonlinear optical systems

doi:10.1088/1674-1056/ace1da

Abstract In nonlinear optical systems, optical solitons have the transmission properties of reducing error rate, improving system security and stability, and have important research significance in future research on all optical communication. This paper uses the bilinear method to obtain the two-soliton solutions of the nonlinear Schrödinger equation. By analyzing the relevant physical parameters in the obtained solutions, the interaction between optical solitons is optimized. The influence of the initial conditions on the interactions of the optical solitons is analyzed in detail, the reason why the interaction of the optical solitons is sensitive to the initial condition is discussed, and the interactions of the optical solitons are effectively weakened. The relevant results are beneficial for reducing the error rate and promoting the communication quality of the system.
