摘要：

We report on the design of a temperature sensor based on a hollow-core optical fiber partially filled with liquid. Our findings demonstrate that partially filling the fiber hollow core with liquids results in a temperature sensor with improved resolution compared to a fully filled fiber. The sensing platform operates based on the thermo-optic effect, and the resolution enhancement is achieved by assessing the combined transmission characteristics of the hollow and liquid-filled fiber sections. We understand that our investigation indicates a promising path for developing new hollow-core fiber-based temperature sensors with better resolution levels.
