A High Temperature Sensor Based on Sapphire Fiber Fabry-Perot Interferometer

IEEE Photonics Technology Letters, 2020
A sapphire fiber high temperature sensor based on Fabry-Perot interference was studied in the paper. A sapphire wafer served as the Fabry-Perot cavity was fixed to the end face of the sapphire fiber. The sensor was encapsulated in an alumina ceramic tube-

Compressible Fabry-Perot refractometer

Applied Optics, 1987
The use of a long, thermally stable Fabry-Perot etalon as a refractometer is considered in detail in this study of the refractive index of air. The etalon consists of two flat plates of fused silica 60 mm in diameter, with a cylindrical spacer made of Zerodur (a polycrystalline glass ceramic of extremely low thermal expansion) 200 mm long.

Physical Explanation of Fabry–Pérot Cavity for Broadband Bilayer Metamaterials Polarization Converter

Journal of Lightwave Technology, 2018
We propose a wideband linear polarization converter in transmission mode by bilayer metamaterial. The polarization converter operates from 0.55 to 1.37 THz with polarization conversion ratio maintaining nearly 100%.

Fast demodulated white-light interferometry-based fiber-optic Fabry-Perot cantilever microphone.

Optics Letters, 2018
We demonstrate a highly sensitive and stable fiber-optic Fabry-Perot cantilever microphone based on fast demodulated white-light interferometry. The cavity length of the low-finesse Fabry-Perot interferometry is absolutely measured by realizing a high ...

A Miniaturized Optical Fiber Tip High-Temperature Sensor Based on Concave-Shaped Fabry–Perot Cavity

IEEE Photonics Technology Letters, 2019
We present a miniaturized optical fiber tip Fabry–Perot interferometer for high-temperature measurement based on a concave-shaped cavity. The fabrication process of the diaphragm-free Fabry–Perot cavity is quite simple, involving only two steps: fusion ...

Fabry-Perot Fringe Enhancement

Applied Optics, 1967
The experimental results are presented to show that it is possible to use a Fabry-Perot interferometer to discriminate multifrequency, uniphase gas laser modulation at frequencies less than the laser's doppler bandwidth. This is done by selecting the F.P. mirror spacing to match the laser cavity. Thus, each F.P. mode discriminates the modulation on its

Fabry-Perot inversion algorithm

Applied Optics, 1979
An algorithm for regenerating the input spectrum from Fabry-Perot data is derived and a few numerical experiments are presented to show how well it works.

Multiplexed holographic Fabry-Perot étalons

Applied Optics, 1992
We discuss a multiplexed holographic Fabry-Perot étalon that includes a multiplexed hologram in a novel holographic Fabry-Perot étalon. Two unique advantages can be achieved by using the multiplexed holographic Fabry-Perot étalon: coherently coupled fabrication of holographic Fabry-Perot mirrors significantly reduces the need to have the nearly flat ...

A Polarization Fabry-Perot Duochromator

Applied Optics, 1970
A two-channel Fabry-Perot interferometer for the measurement of very small displacements of spectral lines has been constructed. Advantage is taken both of the superior throughput and resolution of the Fabry-Perot. The two-channel operation is produced by the use of two concentric polarizers and a rotating analyzer.
