摘要：

A simple and compact temperature sensor based on a Mach-Zehnder modal interferometer has been fabricated by bending a single-mode fiber into a balloon-like configuration. Three different fiber sections, fiber without stripping, fiber with a stripped-off protective coating and fiber with a polyvinyl alcohol (PVA) coating have been utilized, each with a small bending diameter of 1 cm that mimics a balloon-like shape. The PVA-coated segment sensor structure showed the highest sensitivity of similar to-1.492 nm degrees C-1, a fast response time of similar to 2.78 ms and a good resolution of similar to 3 x 10(-4)degrees C, for the temperature range 30 degrees C-55 degrees C, benefiting from the good thermo-optical properties of PVA. This sensor can potentially be used in various temperature monitoring processes such as food industries, chemical analysis, detection of molecular analysis and label-free biomedicine.
