Critical states embedded in the continuum

New Journal of Physics, 2015
We introduce a class of critical states which are embedded in the continuum (CSC) of a one-dimensional optical waveguide array with one non-Hermitian defect. These states are on the verge of being fractal and have real propagation constants.

Nonlinear response from optical bound states in the continuum

, 2019
We consider nonlinear effects in scattering of light by a periodic structure supporting optical bound states in the continuum. In the spectral vicinity of the bound states the scattered electromagnetic field is resonantly enhanced triggering optical ...

Topological evolution of band degeneracies and bound states in the continuum in anisotropic photonic crystal slabs

New Journal of Physics
Topological degeneracies, such as Dirac or Weyl points and exceptional points, play a vital role in photonics and metamaterials due to their unique topological characteristics.

Bound states in the continuum in quantum dot pairs [PDF]

, 2006
It is shown that for two open quantum dots connected by a wire, “bound states in the continuum” of a single electron are formed at nearly periodic distances between the dots.

Dispersive bands of bound states in the continuum

Nanophotonics, 2021
Bound states in the continuum (BICs), i.e. highly-localized modes with energy embedded in the continuum of radiating waves, have provided in the past decade a new paradigm in optics and photonics, especially at the nanoscale, with a range of applications

Propagating bound states in the continuum in dielectric gratings

, 2018
We consider propagating bound states in the continuum in dielectric gratings. The gratings consist of a slab with ridges periodically arranged ether on top or on the both sides of the slab.

All-dielectric structural coloration empowered by bound states in the continuum

Nanophotonics
The technological requirements of low-power and high-fidelity color displays have been instrumental in driving research into advanced coloration technologies.

Photonic bound states in the continuum governed by heating

, 2023
A photonic crystal microcavity with the liquid crystal resonant layer tunable by heating has been implemented. The multiple vanishing resonant lines corresponding to optical bound states in the continuum are observed. The abrupt behaviour of the resonant

Ultra-Sensitive Refractive Index Sensing Based on Quasi-BICs in All-Dielectric Nanorod Array

Photonics
We propose an all-dielectric nanorod array for ultra-sensitive refractive index sensing based on quasi-bound states in the continuum (BICs). The nanorod is fabricated by silicon or silicon with an air hole, i.e., the hollow silicon nanorod.
