本文提出了一种新型结构的光纤光栅——包层折射率调制光纤光栅。
A new type of fiber grating, cladding index modulated fiber grating, is presented in this paper.
新型包层折射率调制光栅可以由包层掺杂的光敏光纤经过侧面紫外曝光制成。
Through exposing the cladding photosensitive fiber to periodic ultraviolet, the new cladding index modulated fiber grating can be formed.
同时，研究结果表明，这种新型包层折射率调制的光纤光栅可以为解决纤芯高光敏光纤光栅的高损耗问题提供一个较好的解决方案。
Meanwhile, the research results show that the new grating can be a solution to the high attenuation problem of the gratings with the high photosensitive fiber core.
