群時延
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.
如寬的反射帶寬這一特點使chirped光纖光柵成爲光纖中的寬帶反射鏡，可用於制作光纖帶通濾波器等光纖通信系統中的關鍵器件；在反射帶寬內具有漸變的群時延這一特點使chirped光纖光柵可作爲光纖色散補償器，補償光纖通信系統中光纖色散，將因光纖色散而展寬的光脈沖壓縮，從而延長通信系統中兩個中繼站之間的距離。
