摘要

? 2022In this paper, a Mach-Zehnder interference (MZI) based on asymmetric taper-shaped ultraviolet glue is proposed for highly sensitive temperature sensing. Due to the small diameter and the deflected two ends of the tapered UV glue, part of the light leaked into the air during the propagation of the UV glue taper, resulting in interference. We tested the temperature sensing of several samples with different parameters. Experimental results show that with the increase of temperature, the wavelength moves linearly to a shorter wavelength. The highest temperature sensitivity can reach ?15 nm/℃, and the linear correlation coefficient is 0.995. The sensor has the advantages of low cost, simple manufacture and higher temperature sensitivity is suitable for temperature measurement.
