Temperature sensor by using alcohol-filled side-hole fiber based Sagnac interferometer

A temperature sensor by using an alcohol-filled side-hole fiber (SHF) based Sagnac interferometer is proposed and experimentally demonstrated. The alcohol liquid is filled into air holes of the SHF. Due to its temperature-dependent refractive index, interference pattern of the Sagnac interferometer shifts at sensitivity of 86.1 pm/°C when temperature is changed in a range between 20°C and 70°C.
