Photonic crystal fiber temperature sensor filled with liquid and silver nanowires

摘要

A localized surface plasmon resonance (LSPR) temperature sensor based on photonic crystal fiber (PCF) filled withliquid and silver nanowires is demonstrated both theoretically and experimentally. Simulation results show that a blueshiftis appeared along with temperature increasing. The resonance wavelength and resonance intensity can be tunedeffectively by adjusting the volume ratios of the liquid constituents. To investigate the sensor’s performance, a largetemperature range from 25℃ to 60℃ is detected in experiment and the sensitivity of -2.08 nm/℃ with figure of merit(FOM) 0.1572 is obtained. The all-fiber device with strong mechanical stability is easy to realize remote sensing bychanging the downlead fiber length, also promising for developing a high sensitive, real-time and distribute fiber sensorin temperature sensing applications.
