- 摘要：In this letter, we proposed a gas refractometer based on optical fiber Fabry–Perot interferometer with an open cavity. The Fabry–Perot cavity is a short section capillary tube spliced between a single-mo245-248de fiber and a side-hole fiber (SHF). The unique cladding of the SHF enables gas entering or leaving the Fabry–Perot cavity freely. The measurement of pressure-induced refractive index change of nitrogen gas has been demonstrated by monitoring the wavelength shift of the interference pattern. The robust and microsize architecture make the interferometer a good candidate for gas sensing applications.
