Bound States in the Continuum in Metasurface Absorbers: A Comparison with Metasurfaces

Advanced Photonics Research, EarlyView.
Bound states in the continuum (BICs) offer a powerful mechanism for enhancing light–matter interactions. This work systematically investigates the radiation characteristics of BICs under both transmission and reflection configurations using multipolar analysis.

Manipulating Fano Coupling in an Opto‐Thermoelectric Field

Advanced Science
Fano resonances in photonics arise from the coupling and interference between two resonant modes in structures with broken symmetry. They feature an uneven and narrow and tunable lineshape and are ideally suited for optical spectroscopy.

Tunable Nanosensor Based on Fano Resonances Created by Changing the Deviation Angle of the Metal Core in a Plasmonic Cavity

Sensors, 2018
In this paper, a type of tunable plasmonic refractive index nanosensor based on Fano resonance is proposed and investigated. The sensor comprises a metal-insulator-metal (MIM) nanocavity with a center-deviated metal core and two side-coupled waveguides ...

Fano resonances in antennas: General control over radiation patterns

, 2013
The concepts of many optical devices are based on the fundamental physical phenomena such as resonances. One of the commonly used devices is an electromagnetic antenna that converts localized energy into freely propagating radiation and vise versa ...

In‐Plane Photonic Crystal Devices using Fano Resonances

Laser & Photonics reviews, 2019
Nanocavity devices enabling concentration of light in a very small volume have resulted in several interesting applications over the past years. Of particular interest are the asymmetric resonance lineshapes known as Fano resonances, which result from ...

Intelligent Stain‐Free Histology on Structural Colorimetric Nanocavities

Advanced Science, EarlyView.
Chen and Gan et al. introduce a label‐free imaging platform using inexpensive Nanocavity‐on‐Silicon (NOS) slides. These slides transform subtle tissue variations into vivid structural colors, enabling high‐contrast histological imaging under a regular optical microscope. This stain‐free approach reveals morphological details comparable to traditional H&

Enhanced optical squeezing from quasi-bound states in the continuum and Fano resonances without nonlinearity

New Journal of Physics, 2019
To achieve a high degree of quantum noise squeezing, nonlinear optical interaction process is often employed. Here, we propose to utilize quasi-bound states in the continuum (quasi-BICs) and Fano resonances to enhance optical squeezing without ...

Manipulation of Emergent Collective Excitations via Composition Control in Mixed MPX3 Correlated 2D Antiferromagnets

Advanced Science, EarlyView.
Transition metal and chalcogen substituents are introduced into 2D antiferromagnet, NiPS3, and comprehensive photoluminescence and Raman spectroscopy studies are conducted to investigate how spin orbit entangled exciton and two magnon scattering evolve as functions of substituent concentration.

Double Fano resonances in nanoring cavity dimers: The effect of plasmon hybridization between dark subradiant modes

AIP Advances, 2014
Dark mode which is subradiant plays a key role in the generation of Fano effect. This study proposes that plasmon interaction between dark modes is a favorable method to generate multiple Fano resonances, where plasmon hybridization leads to the ...
