在经过氢敏化处理的保偏光纤上制作了中心波长在1300nm窗口的光纤布拉格光栅，并对这种保偏光纤布拉格光栅的温度传感特性进行了实验研究与理论分析。结果表明这种光栅可以用作温度传感器，对温度进行测量。和普通的标准单模光纤布拉格光栅一样，它对温度的响应具有很好的线性关系。本实验结果还可以作为对保偏光纤光栅传感特性进一步深入研究的参考。

A fiber Bragg grating (FBG) is inscribed in hydrogen-sensitized polarization maintaining fiber with a peak wavelength of 1300 nm. The temperature sensing characteristics of this polarization maintaining fiber grating were experimentally studied and theoretically analyzed. The result shows that this kind of fiber grating can be used as a temperature sensor for temperature measurement. Since the polarization maintaining fiber grating has a fine linear relationship with temperature,it can replace the single-mode fiber grating and decrease the fabrication cost. This experiment result can be taken as a reference for further study on the polarization maintaining fiber grating.
