N2 - A photonic crystal fiber (PCF) temperature sensor consisting of dual embedded silver wires and based on surface plasmon resonance is designed and investigated by the finite element method. The ionic liquid [BMim] [PF6] and Ag are chosen as the filling liquid and sensitive material, respectively. The properties of the sensors based on the single PCF structure and dual symmetrical PCF structure are determined and discussed. The single PCF structure shows an average spectral sensitivity of 2.033 nm/°C, maximum sensitivity of 3.900 nm/°C, and temperature resolution of 0.0256 °C, whereas the dual symmetrical PCF device has an average spectral sensitivity of 3.166 nm/°C, maximum sensitivity of 5.000 nm/°C, and temperature resolution of 0.0200 °C. In addition, the proposed sensor can realize a extremely wide temperature sensing range of 20–320 °C.
