摘要
本文以变系数非线性薛定谔方程为模型,研究光孤子通过色散垒(阱)与非线性垒(阱)的非线性隧穿效应.数值模拟发现,当光孤子通过非线性势垒时,脉冲能够被有效的压缩.
The nonlinear tunneling of optical solitons through both dispersion barriers (wells) and nonlinear barriers (wells) is investigated by employing the exact solution of the generalized nonlinear Schrodinger equation with variable coefficients.
