摘要/Abstract

摘要： 本文从理论上分析了光纤涂覆层对长周期光纤光栅(long period fiber grating, LPFG)温度灵敏度的影响。根据数值分析法对有、无涂覆层的LPFG透射谱建立仿真模型,对LPFG进行温度传感的模式耦合过程进行分析。结果表明:包层模阶数越大,涂覆层对不同包层模有效折射率的影响越大,进而推断出不同包层模耦合的LPFG谐振峰具有不同的温度灵敏度。仿真结果验证了带涂覆层LPFG中高阶包层模耦合的谐振峰对温度更敏感,具有0.977 nm/℃的高灵敏度,是普通LPFG的10倍左右。涂覆层的存在不仅能保护光纤、提高其机械强度,更重要的是,对于高阶包层模耦合出来的透射峰,涂覆层能够有效提高它的温度灵敏度。同时,该结果对保留涂覆层制备光栅以及聚合物涂覆栅型结构方面的实验研究具有一定的参考意义。

Abstract: The influence of fiber coating on the temperature sensitivity of Long period fiber grating (LPFG) is theoretically analyzed. The transmission spectra of LPFG with and without a coating layer are simulated using numerical analysis, and the mode coupling process of LPFG for temperature sensing is analyzed. The results show that the larger the cladding mode order, the greater the effect of the coating layer on the effective refractive index of different cladding modes. Then it is inferred that the LPFG resonance peaks associated with different cladding modes have different temperature sensitivities. The coating layer protects the optical fiber and improves its mechanical strength. Still, more importantly, the coating layer can effectively enhance the temperature sensitivity of the transmission peaks coupled with higher-order cladding modes. At the same time, the results are useful for experimental studies of gratings prepared by retaining the coating layer and polymer-coated grating structures.
