A high sensitivity temperature sensor based on packaged microfibre knot resonator

Li, Jin; Gai, Liting; Li, Hanyang; Hu, Haifeng


A novel temperature sensor has been proposed based on microfibre knot resonator packaged by polydimethylsiloxane (PDMS). Owing to the high thermal expansion and thermo-optic coefficients of PDMS, the resonant wavelength shifted obviously along with the changing of temperature. The experimental results indicated the approximate linear temperature sensing performance in the range of 24–38 °C and 40–54 °C, with the high sensitivities of 1.408 nm/°C and 0.973 nm/°C, respectively. Due to its...[Show more]
