An actively controlled silicon ring resonator with a fully tunable Fano resonance
APL Photonics, 2017 We demonstrate a novel way to generate Fano resonance with tunable wavelength, extinction ratio, and slope rate. The device is a silicon add-drop microring with two integrated tunable reflectors inside, which form an embedded Fabry-Perot cavity.

The spectral characteristics of a multilayer extrinsic fiber Fabry – Perot interferometer
St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2022 The paper describes the development of an analytical response model of an extrinsic fiber Fabry – Perot interferometer with a multilayer cavity in case of spectral interrogation. The system of equations allowing to calculate the spectral characteristic S(

Demonstration of 3-port grating phase relations
, 2006 We experimentally demonstrate the phase relations of 3-port gratings by investigating 3-port coupled Fabry-Perot cavities. Two different gratings which have the same 1st order diffraction efficiency but differ substantially in their 2nd order diffraction

Fiber Fabry-Perot cavity with high finesse [PDF]
, 2010 We have realized a fiber-based Fabry-Perot cavity with CO2 laser-machined mirrors. It combines very small size, high finesse F>=130000, small waist and mode volume, and good mode matching between the fiber and cavity modes.

Multi‐Mode Deep Strong Coupling in a Multi Quantum Well Fabry–Perot Cavity
Advanced Optical Materials, EarlyView.Multi‐mode deep‐strong coupling is demonstrated in a 166‐well heterostructure that acts as a Fabry–Perot cavity. Even cavity modes couple strongly to the cyclotron resonance, producing large vacuum Rabi splittings and a rich polaritonic spectrum captured by a full Hopfield model.

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering
Advanced Photonics Research, Volume 6, Issue 5, May 2025.Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

All fiber, low threshold, widely tunable single-frequency, erbium-doped fiber ring laser with a tandem fiber Fabry–Perot filter [PDF]
, 1991 An all fiber, widely tunable, single-frequency, erbium-doped fiber ring laser was constructed with a threshold pump power as low as 10 mW. Tuning over more than 30 nm was obtained by applying 0 to 17 dc V to an intracavity fiber Fabry–Perot filter ...
