This paper presents a microgap multicavity Fabry–Pérot interferometric sensor fabricated by wet etching and fusion splicing of single-mode optical fibers. The temperature dependence of the optical thickness measurement of self-assembled thin films can be compensated by extracting the temperature information from the multiplexed temperature sensor. Experimental results demonstrate that thin-film characteristics under temperature variations can be examined accurately. The high-temperature sensitivity of the temperature sensor also enables biosensing under temperature variations. This greatly improves the flexibility in sample handling and provides the opportunity to investigate temperature effects in biological applications.
