Compact fiber biocompatible temperature sensor based on a hermetically-sealed liquid-filling structure

ABSTRACT

Kunjian Cao, Yi Liu, Shiliang QuA compact and robust fiber temperature sensor based on a hermetically-sealed liquid-filling Fabry–Perot (FP) cavity was fabricated by low-cost but efficient processes, including fusion splicing, liquid injection, and fused tapering. Owing to the high thermal optical coefficient (TOC) of the ... [Opt. Express 25, 29597-29604 (2017)]
