Abstract

A deviation S-shaped microfiber was proposed and packaged in a capillary by glycerin solution. The high-temperature sensitivity performance was experimentally demonstrated. With the decrease in ambient temperature from 73.05 °C to 23.46 °C, the resonant dip on the transmission spectra red-shifts continually due to the co-operation between the refractive index increase of glycerol and the thermal expansion of packaging materials. The high sensitivity of ∼11 nm/°C promises high-sensitive monitoring of the slight temperature fluctuation in some specific biological and chemical reaction process.
