| 摘 要： | 分析了布拉格光纤光栅纤芯折射率和光栅反射率随温度和时间变化的规律，应用有关模型提出了加速衰变的概念，并由此建立了相关退火工艺。利用衰变曲线可预测光栅在给定时间和温度下的特性，理论和实验结果相吻合。

| Abstract: | The principle on refractive index of core and reflectivity of FBG changing with temperature and time was analyzed. With some research work on appropriate model, the concept of accelerating decay is raised, upon which a novel annealing process is established. With the data measured, the future characteristic of grating can be given under certain temperature and time. The theoretical and practical results are almost in agreement. |
