International Conference on Optical Communications and Networks, 2019
A high-sensitivity all-fiber Fabry-Perot interferometer (FPI) gas refractive index (RI) sensor based on lateral offset splicing and Vernier Effect is proposed. The sensing head consist of a reference FPI and a sensing FPI. A reference FPI and the sensing

Recording Fabry-Perot Interferometer
Review of Scientific Instruments, 1968A recording interferometer is described in which a direct plot of spectral intensity against wavenumber is obtained without the use of a time base. When used as a double recorder, the instrument records two spectral profiles simultaneously. In this form, the recorder is particularly suited to the comparison of spectral profiles and the measurement of ...

Fiber Fabry-Perot interferometers
Integrated Optics and Optical Fiber Communication, 1981A Fabry-Perot (FP) interferometer or etalon is an optical device that can detect, in a digital way, temperature, pressure, or mechanical vibration via the change in optical path length between two surfaces with high reflectivity. In this paper we report some studies of a fiber Fabry-Perot etalon (FFPE).

Fabry-Perot interferometer surfacing
Optics & Laser Technology, 1972Abstract The Institut d'Optique de Paris has been interested for many years in fabricating flat optical surfaces for Fabry-Perot interferometers. This paper details a few conclusions obtained about pitch surfacing from a study which took place in these laboratories.

Multimirror Fabry–Perot interferometers
Journal of the Optical Society of America A, 1985The addition of one or more partially reflecting mirrors to a traditional two-mirror Fabry–Perot interferometer results in a multimirror Fabry–Perot interferometer. A superposition of all possible multiple reflected beams is described with a general theory for multimirror interferometers, featuring matrices analogous to the theory of multilayer thin ...

Nonlinear Fabry-Perot interferometers
Journal of Physics E: Scientific Instruments, 1982Presents a review of current experimental progress on nonlinear Fabry-Perot interferometry placing particular emphasis on the phenomenon of optical bistability. After a short theoretical introduction outlining physical principles and device uses the authors describe the early experiments on Na, ruby and Kerr media.

The Atomic Fabry-Perot Interferometer
2002Since the realisation in 1995 of an atomic Bose-Einstein condensate (BEC), atom optics has began to take advantage of the remarkable properties of such a coherent matter wave: indeed, the large number of atoms sharing the same quantum state can be described as a classical C-number matter wave.
