群时延
According to gradual group delay, chirped fiber gratings can be used as fiber dispersion compensator for compensating fiber dispersion in fiber communication system and compressing broadened light pulse, accordingly, the distance between two relay stations is extended.
如宽的反射带宽这一特点使chirped光纤光栅成为光纤中的宽带反射镜，可用于制作光纤带通滤波器等光纤通信系统中的关键器件；在反射带宽内具有渐变的群时延这一特点使chirped光纤光栅可作为光纤色散补偿器，补偿光纤通信系统中光纤色散，将因光纤色散而展宽的光脉冲压缩，从而延长通信系统中两个中继站之间的距离。
