单模光纤中啁啾暗孤子的演化特性

The Evolution Feature of Chirp-dark Solition in Single-mode Fiber

本文利用Lagrange-Euler公式研究了形如tanh初始啁啾暗孤子在单模光纤中演化的特性,发现高阶色散有利于渐近暗孤子的形成.

The evolution feature of initial chirp-tanh-dark solition in single-mode fiber is studied by using Lagrang-Euler formulae in this paper. The results show that the hight-order dispersion contributes to the formation of asymptotic dark soliton.
