Abstract

A novel temperature sensor comprising a photonic crystal fiber (PCF) is investigated based on surface plasmon resonance (SPR). The finite element method (FEM) is used to determine the temperature sensitivity of the PCF consisting of different concentrations of the analyte. Coating the sensor with a gold layer on the wall of the liquid channel not only overcomes experimental challenges, but also enhances the temperature sensitivity. The simulation results show that the SPR spectra blue-shift with increasing temperature and the resonance wavelength and confinement loss depend on the thickness of the gold layer. The sensor exhibits remarkable temperature sensitivity up to 3080 pm/°C with a corresponding resolution of 0.01325 °C.
