纤维布拉格栅栏(FBG ) 是一个被动光纤维部件，折射索引沿着纤维长度调制了并且广泛地在察觉到系统的纤维被使用了。高温度的稳定的纤维栅栏为在高温度的使用是有希望的并且吸引广泛的注意。在这份报纸， FBG 在氢被刻写有 248-nm excimer 激光的装载标准单个模式纤维，和改革栅栏通过热处理被获得。改革 FBG 的中央波长的移动与改革 FBG 的温度，和反射率有好线性能几乎在 800 敨 ? 保持未改变 ? 猠牴吗？

英文摘要：

The fiber Bragg grating （FBG） is a passive optical fiber component with the refractive index modulated along the fiber length and has been widely applied in fiber sensing systems. High-temperature stable fiber gratings are promising for uses at high temperatures and attract extensive attention. In this paper, FBGs were inscribed in hydrogen loaded standard single mode fibers with the 248-nm excimer laser, and regenerated gratings were obtained through heat treatment. The shift of the central wavelength of the regenerated FBG had a good linearity with temperature, and the reflectivity of the regenerated FBG could almost keep unchanged at 800 ℃.
