Abstract

We propose a highly sensitive fiber temperature sensor based on a section of liquid-sealed silica capillary tube inserted in a single–multi–single-mode fiber structure. The liquid polymer is filled into the silica capillary tube through two micro-holes drilled by a femtosecond laser. Then the micro-holes are blocked by UV curable adhesive with ultra-small volume. Obvious Mach–Zehnder interference peaks were shown in its transmission spectrum. The proposed fiber temperature sensor can be reliably used for actual point detection owing to its high sensitivity (8.09 nm/°C), good linearity (99.93%), compact size, good mechanical property, high fabrication efficiency, and good repeatability and stability.
