随着光纤光栅的问世,,,光纤通讯日益蓬勃,,,光纤光栅泛起了许多的种类,,,例如啁啾、相移、切趾、取样光栅(SFBG)等等,,,取样光栅由于其传输通道距离稳固,,,通带窄,,,具的极好的波长选择性,,,因而在光波分复用器、光纤激光器、光分插复用器、光解复用器等光器件,,,以及光纤传感,,,光信息交流等手艺领域施展主要作用
取样光纤光栅着实与相当光纤光栅基本上一致,,,差别的地方在于,,,相移光栅是在匀称布拉格光栅的某一点处引入相移,,,导致在反射谱中新开出了一个或者多个窗口,,,窗口的几多与光栅的相移点的几多有关,,,取样光栅在结构上与此相似,,,一段匀称布拉格光栅后接一段正常光纤,,,正常光纤的作用引起一定的相移,,,因而其反射谱泛起出梳状结构,,,在反射窗口中翻开一个个通道。。。通道的个数以及通道距离,,,反射率的巨细与取样的周期、光栅长度、折射率调制深度等相关。。。
