A Tunable Echelle Imager [PDF]
, 2000 We describe and evaluate a new instrument design called a Tunable Echelle Imager (TEI). In this instrument, the output from an imaging Fabry-Perot interferometer is cross-dispersed by a grism in one direction and dispersed by an echelle grating in the ...

Two-Parameter Elliptical Fitting Method for Short-Cavity Fiber Fabry–Perot Sensor Interrogation
Sensors, 2018 To solve the cavity interrogation problem of short cavity fiber Fabry–Perot sensors in white light spectral interrogation with amplified spontaneous emissions (ASEs) as the white light sources, a data processing method, using an improved elliptical

Известия высших учебных заведений России: Радиоэлектроника, 2023 Introduction. One of the directions in Fabry–Perot antenna design consists in increasing its operation frequency range. In the present work, we set out to develop a Fabry–Perot antenna with a smooth gain pattern across a wide frequency range. To that end,

Ultrahigh finesse Fabry-Perot superconducting resonator [PDF]
, 2007 We have built a microwave Fabry-Perot resonator made of diamond-machined copper mirrors coated with superconducting niobium. Its damping time (Tc = 130 ms at 51 GHz and 0.8 K) corresponds to a finesse of 4.6 x 109, the highest ever reached for a ...

Resonance-enhanced spectral funneling in Fabry–Perot resonators with a temporal boundary mirror
Nanophotonics, 2022 A temporal boundary refers to a specific time at which the properties of an optical medium are abruptly changed. When light interacts with the temporal boundary, its spectral content can be redistributed due to the breaking of continuous time ...

Input-output relations for a 3-port grating coupled Fabry-Perot cavity [PDF]
, 2005 We analyze an optical 3-port reflection grating by means of a scattering matrix formalism. Amplitude and phase relations between the 3 ports, i.e. the 3 orders of diffraction are derived.

One mode-model in nanostructures with inclined sidewalls applied to nano Fabry-Perot structures [PDF]
EPJ Web of Conferences, 2023 Metasurfaces are engineered with specific shapes and sizes to interact with light in a unique way. By manipulating the design of the metasurface, it is possible to control optical properties of the surface such as its thermal emissivity.

Distinct Signatures For Coulomb Blockade and Aharonov-Bohm Interference in Electronic Fabry-Perot Interferometers [PDF]
, 2008 Two distinct types of magnetoresistance oscillations are observed in two electronic Fabry-Perot interferometers of different sizes in the integer quantum Hall regime.

Refractive index tip sensor based on Fabry-Pérot cavities formed by a suspended core fibre [PDF]
Journal of the European Optical Society-Rapid Publications, 2009 A Fabry-Perot refractometer based on the suspended core fibre is presented. The Fabry-Perot cavities are formed by a section of suspended core fibre between conventional single-mode fibres.
