色散缓变光纤中脉冲传播特性以及调制不稳定性研究

Modulation Instability and Pulse Transmission Properties in Decreasing Dispersion Fibers

主要研究了不同群色散剖面色散缓变光纤(DDF)中脉冲传输的展宽因子,并将DDF展宽特性的仿真结果与单模光纤(SMF)进行对比;另外分析了二阶色散以及高阶非线性效应在DDF中产生的调制不稳定性,从而对DDF做了一个较为全面的分析.

This paper mainly focuses on the broaden index of various DDF,and compares the simulated results with SMF.What s more,the studies of second order dispersion property and modulation instability induced by higher nonlinear effects in DDF are also included.
