Microcavity phonon polaritons from the weak to the ultrastrong phonon–photon coupling regime

open access: yesNature Communications, 2021
Strong coupling between light and matter can be engineered to influence their properties and behaviour. Here, the authors demonstrate the evolution from weak to ultrastrong coupling of microcavity modes and optical phonons with hexagonal boron nitride ...

Axially symmetrical Fabry-Perot oscillator with multiple devices inserted in dielectric substrate [PDF]

open access: yes, 1997
We investigate an axially symmetrical Fabry-Perot oscillator with active devices inserted in a dielectric substrate for power combining of many more devices in the microwave and millimeter wave frequency range.

A Topological View on Optical and Phononic Fabry–Perot Microcavities through the Su–Schrieffer–Heeger Model

open access: yesApplied Sciences, 2018
Advances in nanofabrication technologies have enabled the study of acoustic wave phenomena in the technologically relevant GHz–THz range. First steps towards applying concepts from topology in nanophononics were made with the proposal of a new ...

Temporal analog of Fabry-Pérot resonator via coherent population trapping

open access: yesnpj Quantum Information, 2021
Ramsey spectroscopy via coherent population trapping (CPT) is essential in precision measurements. The conventional CPT-Ramsey fringes contain numbers of almost identical oscillations and so that it is difficult to identify the central fringe.

Anisotropic Acoustic Plasmons in Black Phosphorus [PDF]

open access: yes, 2017
Recently, it was demonstrated that a graphene/dielectric/metal configuration can support acoustic plasmons, which exhibit extreme plasmon confinement an order of magnitude higher than that of conventional graphene plasmons.

High-Q tunable Fano resonances in the curved waveguide resonator with mirrors with spatially variable reflectivity

open access: yesКомпьютерная оптика, 2023
High-Q Fano resonances are demonstrated, as well as effects similar to electromagnetically induced transparency arising in a curved Fabry-Perot waveguide resonator with variable-reflection mirrors.

Rotman Lens-Fed Fabry-Perot Resonator Antennas for Generating Converged Multi-Mode OAM Beams

open access: yesIEEE Access, 2019
In this paper, we present a Rotman lens-fed Fabry-Perot resonator antennas (FPRA) for generating multi-mode OAM beams with low beam divergence. The Rotman lens works as a beamforming network in the FPRA for the multi-mode OAM operation, significantly ...
