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.
