Abstract
The thermal stability of Type I gratings is increased by postthermal tuning of the grating. Optimization of the procedure leads to gratings that can withstand temperatures as high as 600 degrees C. Aging tests lead to lifetime predictions as high as 25 years with <3 dB reduction at 400 degrees C. Single exponential relaxation is observed. Above 800 degrees C regeneration is obtained.
摘要
通过对光栅进行后热调谐，可以提高 I 型光栅的热稳定性。优化后的工艺可以使光栅耐受高达 600°C 的温度。老化测试可预测其在 400°C 时的使用寿命高达 25 年，且在 3dB 以下的衰减。观察到单指数弛豫。高于 800°C 时可实现再生。
