Abstract

We report what is to our knowledge the first characterization at high temperatures of long-period fiber gratings written in Ge-free air-silica microstructure fiber. The gratings written with the electric-arc technique suffer a low shift of the resonance wavelengths when the temperature is increased from 20 degrees C to 1200 degrees C. This shift is studied and compared with that of a long-period fiber grating written in a standard single-mode fiber by the same technique. Good thermal stability of the grating and of the fiber after annealing at 1200 degrees C for 1 h is demonstrated.

摘要

据我们所知，我们报道了首次在高温下对写入无锗空气-二氧化硅微结构光纤中的长周期光纤光栅的特性进行的研究。当温度从20摄氏度升高到1200摄氏度时，采用电弧技术写入的光栅的共振波长发生了较小的偏移。我们对这种偏移进行了研究，并与采用相同技术写入标准单模光纤中的长周期光纤光栅的偏移进行了比较。结果表明，在1200摄氏度下退火1小时后，光栅和光纤具有良好的热稳定性。
