色散缓变光纤中指数型损耗对孤子传输特性的影响

Influence of exponential loss on the propagation properties of soliton in the fibers with slowly decreasing dispersion

本文用行波解法求解了含指数型损耗的色散缓变光纤的NLS方程 ,由此孤子解讨论了指数型损耗对孤子传输特性的影响。

In this paper,the travelling wave method is used to solve the NLS equation with slowly decreasing dispersion and exponential loss.According to the solution the influence of exponential loss on the propagation properties of soliton with slowly decreasing dispersion is discussed in detail.
