The fabricated device bases its operation on the optical resonances of a capillary optical microresonator that has the ability to couple the evanescent light from an optical fiber tapers with a central diameter in the range of 3-5 μm which excites the resonant modes WGMs inside the cavity. The microcavity was manufactured using a heating-pressurization technique by a system built to measure which allowed reaching a minimum wall thickness in the central region of the order of 19.78 μm with a sensitivity of the order of 0.5567 nm/bar.
