Bound states in the continuum (BICs) are a striking example of how a solution to a simple
problem of quantum mechanics, obtained about a century ago, can serve as an incentive to …

Bound states in the continuum (BIC) have garnered considerable attention recently for their
unique capacity to confine electromagnetic waves within an open or non-Hermitian system …

Recently, based on the selective excitation of the guided mode, researchers realized quasi-
bound states in the continuum (quasi-BICs) in all-dielectric compound grating waveguide …

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 …

Herein, we establish a hybrid coupling model (HCM) containing both near-and far-field
couplings to describe the electromagnetic response of the coupled-grating system …

We consider bound states in the continuum (BICs) in grating composed of infinitely long
silicon rods of rectangular cross-section. We reveal merging off-Γ Friedrich-Wintgen BIC with …

To control and enhance light–matter interactions at the nanoscale, two parameters are
central: the spectral overlap between an optical cavity mode and the material's spectral …

Perfect absorbers, which can achieve total absorption of all incoming energy, have been
extensively studied in the last decades for various important technologies in general wave …

The realization of bound states in the continuum (BICs) in optical systems has been relying
mainly on symmetry breaking. In contrast, another mechanism, known as resonance-trapped …

We study the effect of structural disorder on the transition from the bound states in the
continuum (BICs) to quasi-BICs by the example of the periodic photonic structure composed …
