求翻译：相移光纤光栅是在常规布拉格光栅的某一特定部位引入一定的相移（折射率分布不连续），在其透射谱带中开出一个或多个线宽极窄的透射窗口。这种光栅具有很好的波长选择性, 插入损耗低,而且与偏振态无关。在光栅中心引入相位差为 的相移光栅又称 光栅。图9.10是 相移光纤光栅的反射谱。是什么意思？

Phase shift of the fiber grating is to introduce a certain phase shift in a particular part of the regular Bragg grating (refractive index distribution is not continuous), to open their transmission bands of one or more of the line width of very narrow transmission window. This grating has a good wa
