Directional Flow of Confined Polaritons in CrSBr

Advanced Materials, EarlyView.
CrSBr, a layered magnetic semiconductor, naturally channels self‐hybridized excitonpolaritons into highly directional flow. Its intrinsic optical anisotropy, high refractive index, and strong lightmatter coupling enable long‐range guided modes along the a‐axis, with propagation lengths set by their excitonphoton admixture.

Engineering photonic Floquet Hamiltonians through Fabry–Pérot resonators

New Journal of Physics, 2016
In this paper we analyze an optical Fabry–Pérot resonator as a time-periodic driving of the (2D) optical field repeatedly traversing the resonator, uncovering that resonator twist produces a synthetic magnetic field applied to the light within the ...

Enhanced Entanglement in Hybrid Cavity Mediated by a Two-way Coupled Quantum Dot

Open Physics, 2020
We investigate theoretically the entanglement in a hybrid Fabry-Perot cavity system. A membrane in the cavity acts as a mechanical resonator, and a two-level quantum dot is coupled to both the cavity mode and the mechanical resonator.

Stability Diagram of the Fabry-Perot Resonators

IEEJ Transactions on Sensors and Micromachines, 2006
The stability diagram of the Fabry-Perot resonator composed of two spherical mirrors is calculated by the Kirchhoff diffraction integral equation. We have derived the proper equation from the integral and diagonalized it. It has also been calculated the dependence of the stability diagram on the Fresnel number.

Strong Coupling in all‐Polymer Planar Microcavities

Advanced Optical Materials, EarlyView.
Strong Coupling has been achieved in an all‐polymer microcavity with dielectric contrast Δn = 0.33 doped with TDBC. A Rabi splitting of 39 meV has been measured opening novel perspectives for polymer photonics. ABSTRACT In this work, strong coupling effect is observed in all‐polymer planar microcavities incorporating TDBC J‐aggregates dispersed into ...

High Gain Slot Array with Fabry-Perot Cavity Feeding Circuit

International Journal of Antennas and Propagation, 2016
A new approach for designing slot arrays using a Fabry-Perot cavity for the feeding circuit is presented. The proposed array has simpler and smaller feeding circuit compared to conventional feeding networks that have multiple dividers or combiners.

Omnidirectional Ultra‐Broadband Cu/TiO2 Metasurface Absorbers for High‐Efficiency Solar Thermal Conversion and Photothermal Plasmon‐Driven Catalysis

Advanced Optical Materials, EarlyView.
Metasurface shows selective solar–thermal energy conversion with high‐activity solar/laser‐driven chemistry. The breakthrough is co‐designing broadband FP‐cavity + plasmonic LSPR/SLR resonances in an ultra‐thin metamaterial so that it not only harvests the most efficient proportion of solar radiation but also suppresses mid and IR emissivity. Moreover,
