摘要
对使用简支梁调谐光纤光栅(FBG)波长的计算方法进行了分析,改进了传统计算公式,给出了计算光栅波长调谐量的解析式。与传统算法相比,改进算法可以直接通过梁的长度变化量计算得到波长调谐量,因此应用更加简便,可以更为直接地指导调谐实验。
The principle of the tunability of FBG using a freely supported beam is analyzed
theoretically, and the traditional formula are improved by analytical equations which are more
simple when computing the wavelength tuning of FBG, and it is helpful to guide tuning
experiments more directly.
