Optical fibers are widely used for temperature sensing due to their intrinsic temperature sensitivity. However, such sensitivity is an issue when one wants to sense other parameters, as for example, the refractive index of a sample. Thus, somehow it is necessary to compensate the effect of temperature. For this reason, different dual-parameter fiber optic sensing schemes have been reported in the literature. To the best of our knowledge, the majority of such schemes need two sensors (one for reference) or two platforms to monitor two parameters. In this work, we demonstrate that a single optical fiber interferometer is capable of monitoring two parameters (refractive index and temperature) simultaneously. Said interferometer is built with a short segment of coupled-core multicore fiber fusion spliced at the end of a conventional single mode fiber. In the multicore fiber, two supermodes are excited with similar intensities. As a result, the interference pattern is truly sinusoidal with high visibility. Temperature induces a shift to the interference pattern and refractive index alters the amplitude of such a pattern. We have investigated analytically and experimentally the performance of our dual-parameter sensor under different fabrication conditions and its multiple practical applications. For example, it can be used to measure the thermo-optic coefficient of gels, polymers or liquids. Such results will be presented at the conference.
