Narrow-band and highly absorbing fano resonance in a cavity-coupled dielectric metasurface

open access: yesMaterials Research Express, 2023
Metamaterial resonance offers a flexibility in engineering the frequency and bandwidth of light absorption for a variety of optoelectronic applications such as wavelength-selective photodetection, optical sensing and infrared camouflaging etc.

Optical Responses From Zero Optical‐Path‐Length Object

open access: yesNanophotonics, Volume 15, Issue 15, 13 August 2026.
This work address a fundamental question—what is the ultimately minimal embodiment of optical objects that produce useful optical effects? In fact, such an object does not require nonzero physical and optical‐path‐length volume as opposed to the conventional perception.

Interplay Between Bound State in the Continuum and the Generalized Kerker Effect in Plasmonic Metasurfaces

open access: yesAdvanced Photonics Research, Volume 7, Issue 8, August 2026.
A plasmonic metasurface comprising gold cylinders of tailored dimensions exhibits simultaneously the generalized Kerker effect and a bound state in the continuum, allowing for a detailed study of the subtle interplay between these phenomena. The numerical simulation results are in good agreement with experimental measurements, and the underlying ...

Sharp Fano resonances in THz metamaterials

open access: yesOptics Express, 2011
We report on the occurrence of sharp Fano resonances in planar terahertz metamaterials by introducing a weak asymmetry in a two gap split ring resonator. As the structural symmetry of the metamaterial is broken a Fano resonance evolves in the low-frequency flank of the symmetric fundamental dipole mode resonance.

Extreme Polaritonic Interactions in a Room‐Temperature Designable Sub‐Nanocavity Quantum Electrodynamic Platform

open access: yesAdvanced Science, Volume 13, Issue 44, 7 August 2026.
 A nanoparticle‐cluster‐on‐mirror (NPcoM) serves as a functionally deterministic sub‐nanocavity that emulates picocavities, enabling extreme light–matter interactions and polaritonic phenomena. ABSTRACT Pushing nanoscale optical confinement to its ultimate limits defines the regime of nano‐cavity quantum electrodynamics (nano‐cQED), where light‐matter ...

Nonlinearly Tunable Fano Resonance in One-Dimensional Light Tunneling Heterostructure

open access: yesPhotonics
In this paper, we theoretically investigate nonlinearly tunable Fano resonance by employing a light tunneling heterostructure with one-dimensional defective photonic crystals and a lossy metallic film. We find that the phenomenon of Fano resonance can be

Observation of Excitonic Instability in a Monolayer Ta2NiSe5 With Strain Disorder

open access: yesAdvanced Science, Volume 13, Issue 43, 3 August 2026.
Monolayer Ta2${\rm Ta}_2$NiSe5${\rm NiSe}_5$ sustains an excitonic insulating phase up to 190 K, with Raman signatures of gap opening and critical excitonic fluctuations. Thickness‐independent large gap ratios highlight strong exciton‐phonon coupling, while substrate‐induced strain disorder depresses Tc, establishing monolayer Ta2${\rm Ta}_2$NiSe5${\rm

Kondo Screening and Coupling of Spin States on Graphene Nanoribbon

open access: yesphysica status solidi (RRL) – Rapid Research Letters, Volume 20, Issue 8, August 2026.
Coupling of spin states, at the terminus of 7‐AGNR, is manifested by a continuous presence of Kondo resonance across the line profile of the two magnetic sites. This ubiquitous presence of the Kondo effect indicates mediated exchange interactions that may lead to exotic magnetic ordering at the peripheral atoms.

Fano-Like Resonance in an All-in-Fiber Structure

open access: yesIEEE Photonics Journal, 2019
We achieve Fano-like resonances in an all-in-fiber structure embedded with an in-line Mach-Zehnder interferometer (MZI). A fiber Bragg grating is inserted into MZI's one arm to form a resonance, which functions as the discrete state of the Fano ...
