Paper Abstract
A high sensitive temperature sensor based on D-shaped microfiber with high birefringence is proposed and demonstrated. In order to obtain D-shaped microfiber, we polish a single mode fiber (SMF) and then taper down the polished region into micrometer size. By utilizing Sagnac loop interferometer, we achieve high refractive index (RI) sensitivity of 9951nm/RIU. Further, we realize temperature detection assisted by sucrose solution with high thermo-optic coefficient. Experimental results demonstrate high temperature sensitivity up to -0.98921nm/°C within the range of 22°C-60°C. The sensor is featured with high sensitivity, compact structure and easy fabrication.
