Paper Abstract

A high-sensitivity temperature sensor based on fiber Bragg gratings (FBGs) in liquid-filled photonic crystal fibers (PCFs) is proposed. PCF is designed using the full-vector finite-element method. To achieve the maximum difference of the core-mode effective index of PCF as the temperature change, the structural parameters of PCF are optimized via genetic algorithms. The calculated Bragg wavelength shift (BWS) value of FBGs in liquid-filled PCF is 263  pm/°C as the temperature changes from −15°C to 65°C.
