We show refractive-index tip sensor of an all Fabry-Perot(FP) interferometer made by conventional fiber and hollow-core photonic crystal fiber. We obtained two cavities that were formed at the conventional fiber tip using arc discharges by splicing tecnique and generate a Modified Intrinsic Fabry-Perot Interferometer(MIFPI). As a result of the interaction between these cavities was obtained a refractive index sensor. The MIFPI tip was immersed into a water-glycerol concentrations, these mixtures provided a refractive index variation. In addition, the MIFPI presents good resolution and sensitivity. The structure offers compactness, robustness, high repeatability, and stability measurement.
