Sech型光脉冲在光纤─光栅对中的传输和变换

Transformation and Compression of Sech Type Pulse Through Fiber - Grating Pair System

借助脉冲的等效时间复参数讨论了Ｓｅｃｈ型光脉冲通过光纤─光栅对系统后的传输和变换特性，给出了脉冲压缩的最佳条件，为处理非高斯型光脉冲经过线性系统的传输提供了一种有效的方法。

In this paper, the equivalent temporal complex parameter for sech type pulse is introduced,pulse transformation property and optimum compression condition is derived when it pass through fiber - grating pair system.,It is a useful method for treating non - Gaussian pulse propagation through second - order system.
