An autocorrelator based on a Fabry-Perot interferometer

open access: yesOptics Express, 2018
An autocorrelator based on a Fabry-Perot interferometer is proposed for ultrashort pulse measurement. Main features of this autocorrelator due to the superposition of multiple pulses were investigated experimentally and theoretically.

Anticaustics in a Fabry–Perot interferometer

open access: yesJournal of the Optical Society of America A, 2022
We address the response of a Fabry–Perot interferometer to a monochromatic point source. We calculate the anticaustics (that is, the virtual wavefronts of null path difference) resulting from the successive internal reflections occurring in the system.

An investigation of chirped fibre Bragg gratings Fabry-Perot interferometer for sensing applications [PDF]

open access: yes, 2005
Fibre interferometer configurations such as the Michelson and Fabry-Perot (FP) have been formed using uniformed and chirped Fibre Bragg Gratings (FBG) acting as partial reflectors. As well as increasing the dynamic range of the interferometer, chirped

High-spectral-resolution Fabry-Pérot interferometers overcome fundamental limitations of present volcanic gas remote sensing techniques

open access: yesFrontiers in Earth Science, 2023
Remote sensing (RS) of volcanic gases has become a central tool for studying volcanic activity. For instance, ultraviolet (UV) skylight spectroscopy with grating spectrographs (GS) enables SO2 (and, under favourable conditions, BrO) quantification in ...

Analytical method to find the optimal parameters for gas detectors based on correlation spectroscopy using a Fabry-Perot interferometer [PDF]

open access: yes, 2007
Several designs of infrared sensors use a Fabry-Perot Interferometer (FPI) to modulate the incident light. In this work we analyse the particular case where the FPI fringes are matched with very well defined ro-vibrational absorption lines of a target ...

Analysis of Embedded Optical Interferometry in Transparent Elastic Grating for Optical Detection of Ultrasonic Waves

open access: yesSensors, 2021
In this paper, we propose a theoretical framework to explain how the transparent elastic grating structure can be employed to enhance the mechanical and optical properties for ultrasonic detection.

Characterization of a novel three-section tunable slotted fabry-perot laser [PDF]

open access: yes, 2010
A novel three-section tunable slotted-Fabry-Perot laser has been examined. Characterizations of the linewidth, SMSR and RIN indicate that this type of laser may be a suitable source for dynamic networks employing advanced optical modulation ...

Optimal Design of an Hourglass in-Fiber Air Fabry-Perot Microcavity—Towards Spectral Characteristics and Strain Sensing Technology

open access: yesSensors, 2017
An hourglass in-fiber air microcavity Fabry-Perot interferometer is proposed in this paper, and its second reflecting surface of in-fiber microcavity is designed to be a concave reflector with the best curvature radius in order to improve the spectral ...
