Abstract
A smart temperature sensor is performed based on the high birefringence (HB) fiber loop mirror. The sensing can be achieved by simply detecting the light intensity, utilizing a single mode laser diode (LD) as the source. In the range of 25°C-35°C, the resolution and linear regression are 0.05°C and 0.9986, respectively. The sensor can be employed to precise temperature measurement and the range can expand further when selecting shorter HB fiber in the loop mirror.
