摘要
报道一种简单的光纤光栅对参考法测定光纤光栅布拉格(Bragg)波长的位移的方法,其原理是利用一个布拉格波长可调谐的光纤光栅去跟综另一个光纤光栅布拉格波长的变化,测得的光栅布拉格波长的温度灵敏度为0.0088nm/℃。
A simple fiber grating pair referencing method for measuring fiber grating Bragg wavelength shifts is reported. The temperature sensitivity of fiber grating Bragg wavelength was determined to be 0 0088 nm/℃, which was coincident very well with the experimental result measured using a fine tunable laser diode.
