Abstract
In this article, an optical fiber temperature sensor with high sensitivity and a wide detection range based on a Mach-Zehnder interferometer (MZI) is proposed and experimentally demonstrated. The difference and connection between the calculation results and the experimental results have been discussed systematically. It is found that the sensor is applicable to detect temperature change in the range of 30 °C–100 °C with a sensitivity of −0.06 nm/°C. Furthermore, the maximum sensitivity could reach up to −0.196 nm/°C in the range from <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$- 40\,\,^{\circ }\text{C}$ </tex-math></inline-formula> to 50 °C by filling ethanol. The proposed sensor has the advantages of good repeatability, wide detection range, and high sensitivity, which indicates that it has great potential prospects in the field of temperature sensing.
