Bound states in the continuum (BICs) have attracted attention in photonics owing to their
interesting properties. For example, BICs can effectively confine light in a counterintuitive …

The photonic spin Hall effect (PSHE) plays an important role in both fundamental science
and precision metrology. In this paper, we theoretically propose a polarization-dependent …

Optical resonators with high quality (Q) factors are paramount for the enhancement of light–
matter interactions in engineered photonic structures, but their performance always suffers …

Plasmon‐free surface‐enhanced Raman spectroscopy (SERS) assisted by charge‐transfer
(CT) resonance in semiconductors has drawn considerable attention in the past decades …

Bound states in the continuum (BICs) of plasmonic systems offer a powerful method for
enhancing light–matter interaction at the nanoscale. The recent emergence of flatband quasi …

In this work, a doubly resonant photonic crystal (PhC) cavity using the merged bound state in
the continuum (BIC) is proposed to obtain a higher second harmonic generation (SHG) …

By virtue of the widely tunable band structure, dangling-bond-free surface, gate electrostatic
controllability, excellent flexibility, and high light transmittance, 2D layered materials have …

High-contrast refractive indices are pivotal in dielectric metasurfaces for inducing various
exotic phenomena, such as the bound state in the continuum (BIC) and electric mirror (EM) …

Herein, we achieve giant Goos-Hänchen (GH) shifts driven by Fabry-Perot quasibound
states in the continuum (quasi-BICs) in double-layer gratings. Based on the hybrid coupling …

Bound states in the continuum (BICs) with an infinite quality factor (Q factor) and lifetime are
demonstrated as far-field polarization singularities in momentum space. Unidirectional …
