|
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。
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.
