Abstract

Excessive nonlinear drift in optical communication systems can lead to splitting of solitons and coexistence of multiple solitons, thereby affecting communication quality. In this paper, we investigate the nonlinear dynamic characteristics of three-soliton interactions in optical fibers. Firstly, we obtained exact three-soliton solution of the nonlinear Schrödinger equation. Then, we conduct theoretical simulations of the formation process of those obtained three solitons. The effects of initial phase, initial spacing and initial amplitude on the interaction of three solitons are discussed, and the evolution of three solitons in optical fibers is analyzed. The transmission characteristics of the interaction of three solitons are studied using theoretical analysis. The relevant conclusions will enrich people’s understanding of the interaction characteristics of multiple solitons and provide theoretical reference for experimental research.
