摘要
擦除温度和再生温度相同时, 在800~950 ℃温度区间内, 光纤光栅的擦除时间和再生完成时间均随处理温度呈指数衰减。利用再生完成时间拟合函数, 得到紫外载氢标准通信光纤光栅的再生阈值温度为805 ℃, 并且当处理温度在855~905 ℃之间时, 不同温度下制得的再生光纤光栅的反射率大小服从高斯分布, 定量描述了光纤光栅再生的整个过程。提出了一种制作高反射率再生光纤光栅的方法, 当擦除温度和再生温度不同时, 该方法可将紫外载氢标准通信光纤上的再生光纤光栅的反射率从20%提高到43%。
Abstract
The erasing time and the regeneration complete time of fiber grating exponentially decay with temperature in the temperature interval of 800-950 ℃ when the erasing temperature and the regeneration temperature are the same. According to the fitting function of regeneration complete time, the regeneration threshold temperature of ultraviolet hydrogen loading standard communication fiber grating is 805 ℃. The reflectivity of regenerated fiber grating obeys Gaussian distribution when the treatment temperature is set between 855-905 ℃, which describes the whole regeneration process of fiber grating quantitatively. When the erasing temperature and the regeneration temperature are different, a new method to create a regenerated fiber grating with high reflectivity is obtained, and the method can improve the reflectivity of regenerated fiber grating used in ultraviolet hydrogen loading standard communication fiber from 20% to 43%.
