Input-output relations for a 3-port grating coupled Fabry-Perot cavity [PDF]

open access: yes, 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.

Millimeter-long fiber Fabry-Perot cavities

open access: yesOptics Express, 2016
We demonstrate fiber Fabry-Perot (FFP) cavities with concave mirrors that can be operated at cavity lengths as large as 1.5mm without significant deterioration of the finesse. This is achieved by using a laser dot machining technique to shape spherical mirrors with ultralow roughness and employing single-mode fibers with large mode area for good mode ...

Two-Parameter Elliptical Fitting Method for Short-Cavity Fiber Fabry–Perot Sensor Interrogation

open access: yesSensors, 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

Enhanced spontaneous emission from quantum dots in short photonic crystal waveguides [PDF]

open access: yes, 2012
We report a study of the quantum dot emission in short photonic crystal waveguides. We observe that the quantum dot photoluminescence intensity and decay rate are strongly enhanced when the emission energy is in resonance with Fabry-Perot cavity modes in

Realization of double Fano resonances with a InSb-doped Fabry-Perot cavity

open access: yesResults in Physics, 2022
In this paper, a one-dimensional photonic structure is proposed for the realization of double Fano resonance (DFaR), which can be tuned by an external magnetic field and temperature.

Optical vernier technique for in-situ measurement of the length of long Fabry-Perot cavities [PDF]

open access: yes, 1998
We propose a method for in-situ measurement of the length of kilometer size Fabry-Perot cavities in laser gravitational wave detectors. The method is based on the vernier, which occurs naturally when the laser incident on the cavity has a sideband.
