摘要
设计了一种光子晶体光纤(PCF)结构,基于新结构PCF和表面等离子体共振(SPR)效应实现了温度与磁场双参量传感。采用全矢量有限元方法对该传感器的理论模型进行了分析,结果表明,当温度在20~50 ℃内时,传感器的温度灵敏度可达-493.6 pm/℃;当磁感应强度在20~300 Oe内时,传感器的磁场灵敏度可达82.69 pm/Oe。
Abstract
A novel photonic crystal fiber (PCF) structure is designed. A sensor based on the newly designed PCF and surface plasmon resonance (SPR) is proposed, which is applied to temperature and magnetic field detection. The theoretical model is analyzed by the full-vector finite element method. The results demonstrate that the temperature sensitivity is -493.6 pm/℃ with temperature from 20 ℃ to 50 ℃, and the magnetic field sensitivity is 82.69 pm/Oe with magnetic field from 20 Oe to 300 Oe.
