拉曼散射与自陡峭效应对皮秒孤子传输特性的影响∗
Influence of Raman scattering effect and self-steep ening effect on the propagation characteristic of picosecond solitons
摘要
Abstract
By solving the higher-order nonlinear Schrödinger equation (NLSE), including Raman gain and self-steepening effect, the influence of the combined effect of Raman gain and self-steepening on the propagation characteristic of soliton pulse is simulated by the software of MATLAB. Results show that self-steepening effect can produce temporal shifts of the soliton and also can lead to the breakup of higher-order solitons through the phenomenon of soliton fission. Meanwhile, the Raman gain changes the propagation characteristic of optical soliton and inhibits the self-steepening effect, resulting in the increase in pulse width, and the decrease in pulse offset. As a result, the required propagation distance for higher-order soliton decaying into fundamental solitons is increased under the condition of Raman gain.关键词
