A Bragg grating in a photonic crystal fiber was written and its dependence with temperature and strain analyzed. The two observed Bragg wavelengths correspond to a fundamental and a higher-order mode in the optical fiber. The temperature and strain calibration curves for both modes are measured and found to be distinct. The general properties of gratings in these fibers, and their implications, are enunciated.
在光子晶体光纤中写入了布拉格光栅，并分析了其与温度和应变的关系。观察到的两个布拉格波长对应于光纤中的一个基模和一个高阶模。测量了这两种模式的温度和应变校准曲线，发现它们是不同的。阐述了这些光纤中光栅的一般特性及其影响。
