Abstrakt: temperature sensor is demonstrated and fabricated by coating the single-mode tapered optical fiber with temperature-sensitive silicone rubber. It works on the change of the evanescent fields in the tapered optical fiber. Small changes in the refractive index of coating film greatly influence the power of evanescent fields, which modulate the transmission optical power in the waist region. The range of temperature measured is from −20 °C to 70 °C. The results show that the temperature sensor has high temperature sensitivity (0.012 mW/°C) and good repeatability. [ABSTRACT FROM AUTHOR]
