摘要
通过对载氢光敏光纤的光致交直流折射率改变量与曝光时间的关系进行实验数据整理,得出改变直流折射率调制实现相移的方法,并对均匀相位掩模板与啁啾相位掩模板实现的直流相移光栅进行应用研究。
This paper studies the relationship between UV photo-induce direct current (DC) and alternate current (AC) refractive index changes of single mode hydrogen loading fiber, based on the experiment results, it proposes a novel way of achieving phase shift in FBG by increasing DC refractive index, analyzes the difference of traditional discrete phase and DC phase shift relatively for the application of uniform phase mask and chirp phase mask.
