Ruifeng Zhao, Li Pei, Zhuoxuan Li, Tigang Ning , Linyong Fan, Weiwei Jiang
  • Abstract:
    A low cost, compact and lossless temperature sensor based on twin-core fiber(TCF) is demonstrated and manufactured by splicing two single mode fibers(SMF) to the ends of a piece of TCF. The extinction ratio of the comb transmission spectrum is bigger than 15dB. The operating temperature range from to is tested and the temperature sensitivity of below 90℃ and above 90℃ is obtained. Finite element method (FEM) is used to calculate the propagation constant of the two supermodes, which is consistent with the comb transmission spectrum of the experiment.
