强脉冲在光纤光栅中的传输特性

Transmission Properties of the Strong Pulse in Fiber Gratings

利用数值模拟的方法 ,计算分析了强高斯脉冲在光纤光栅中的传输特性 ,研究了强高斯脉冲向基态和高阶孤子的转化和传输 ,分析了光栅带外孤子的特点 。

Using numerically calculation, it is proved that the bound and high order soliton might be formed when Gauss pulse propagated in optical fiber grating though there are extremely strong GVD around the photo band gap. The characteristic of the fiber soliton is analysed, and then the applications on the WDM system is put forward.
