由于相位模板法仅使用一个光学器件 ,因而减少了光纤光栅制造系统的复杂性 ,是光纤布拉格光栅写入法中最有前途、使用最广泛并且具有本征稳定性的一种方法 .本文总结了相位模板技术及各种光纤布拉格光栅的写入 .值得注意的是在相位干涉法中 ,只用一块相位模板 ,就可以调整写入光纤布拉格光栅的波长 .在这些系统中 ,写入光纤光栅的紫外线 ( UV )干涉条纹经由一些光学元件 ,其中 ,相位模板的作用通常是± 1级衍射光的分束器 Because the phase template method uses only one optical device, it reduces the complexity of the fiber grating manufacturing system and is the most promising, the most widely used and inherently stable method in fiber Bragg grating writing method.This paper summarizes Phase template technology and various fiber Bragg grating writing.It is noteworthy that in the phase interference method, only a phase mask, you can adjust the wavelength of the written fiber Bragg grating in these systems, the write fiber grating Ultraviolet (UV) interference fringes pass through some optical elements, where the phase mask typically functions as a ± 1 order diffracted beam splitter
