摘要: A miniature fiber-optic Fabry-Perot interferometer (MOFPI) fabricated by splicing a hollow silica tube (HST) with inner diameter of 4 µm to the end single-mode fiber is investigated and experimentally demonstrated. The theoretical relationship between free spectrum range length HST verified fabricating several MOFPIs different lengths. We characterize for temperature, liquid refractive index, strain. Experimental results show that sensitivities strain are 16.42 pm/°C,–118.56 dB/RIU, 1.21 pm/µe, respectively.
