In this work, a hybrid Fabry-Perot interferometer based on a novel four-bridge microstructured fiber is presented and
characterized. The characterization of this cavity is performed in the L-band using two different instruments: an optical
spectrum analyzer and an optical backscatter reflectometer. The Fabry-Perot output signal presents linear variation with
temperature changes (sensitivity 9.8-11.9 pm/ºC), variation with the polarization states of light and high stability.

A hybrid Fabry-Pérot cavity sensing head based on a four-bridge microstructured fiber is characterized for temperature sensing. The characterization of this cavity is performed numerically and experimentally in the L-band. The sensing head output signal presents a linear variation with temperature changes, showing a sensitivity of 12.5 pm/°C. Moreover, this Fabry-Pérot cavity exhibits good sensitivity to polarization changes and high stability over time.
