光纤非线性色散对类明孤子传输特性的影响
By use of the modified nonlinear Schrodinger equation, we have investigated numerically the effect of nonlinear dispersion, i.
本文采用包含延迟非线性响应时间（即等效的非线性色散）的非线性薛定谔方程，利用数值模拟从理论上系统地分析了非线性色散对孤子在有机高聚物中的形成及传输特性的影响，结果表明当有机高聚物具有较大的非线性色散时，与在一般无机材料光纤等具有较弱非线性色散下形成飞秒孤子的峰值功率条件相比较，必须较大地提高峰值功率才能实现非线性色散、群速度色散、自相位调制三者相互补偿下的孤子传输。
The results show that the ultrashort pulse would be narrow in the normal dispersion if the parameter of second-order nonlinear dispersion was less than zero,and the effects of its was gradually changing with the propagation distance getting smaller and smaller,and the pulse would be width if the parameter of fake-quintic nonlinearity.
结果表明,在正常色散区,二阶非线性色散系数为负时使脉冲变窄,而且它对脉冲影响的程度是随着传输距离不断变化的,影响越来越小;赝五阶非线性系数为负时使脉冲展宽,但与二阶非线性色散项相比影响较小;而自陡系数取值的可正、可负出现了使脉冲在传输过程中其中心位置前后沿均可偏移的现象。
The influence of dispersive magnetic permeability on propagation of untrashort pulses in metamaterials is mainly in that it leads to the appearance of the pseudo-χ (5) , self-steepening (SS) and second-order nonlinear dispersion terms in the propagation equations.
结果表明,在反常色散情形,赝五阶非线性在异向介质的负折射区中增大了调制频谱的范围及增益值,这与常规正折射介质中出现的现象正好相反;自陡峭效应在异向介质中有可能为负值,但无论正负,也无论在正折射区还是负折射区,它都抑制调制不稳定性的产生;二阶非线性色散效应在正、负折射区中分别促进和抑制调制不稳定性的产生。
Further,we study the influence of the controllable self-steepening effect and the second-order nonlinear dispersion on the formation and propagation of dark solitons in metamaterials.
