Higher-Order Nonlinear Effects on Optical Soliton Propagation and Their Interactions

扫码查看
When pursuing femtosecond-scale ultrashort pulse optical communication,one cannot overlook higher-order nonlinear effects.Based on the fundamental theoretical model of the variable coefficient coupled high-order nonlinear Schrödinger equation,we analytically explore the evolution of optical solitons in the presence of high-order nonlinear effects.Moreover,the interactions between two nearby optical solitons and their transmission in a nonuniform fiber are investigated.The stability of optical soliton transmission and interactions are found to be destroyed to varying degrees due to higher-order nonlinear effects.The outcomes may offer some theoretical references for achieving ultra-high energy optical solitons in the future.
