Interfering resonances and bound states in the continuum

Physical Review A, 1985
We use Feshbach's theory of resonances to demonstrate that bound states in the continuum (BIC's) can occur due to the interference of resonances belonging to different channels. If two resonances pass each other as a function of a continuous parameter, then interference causes an avoided crossing of the resonance positions and for a given value of the ...

Photonic waveguides with bound states in the continuum

2024 24th International Conference on Transparent Optical Networks (ICTON)
Recent research on bound states in the continuum (BICs) in photonic waveguides relied mainly on structures that exhibit the effect of lateral leakage. However, the propagating BICs that are supported in such systems have some limitations: they are localized in or in the vicinity of high-refractive-index materials, they are observed as quasiTM polarized

Multibranch Elastic Bound States in the Continuum

Physical Review Letters
Constructing a highly localized wave field by means of bound states in the continuum (BICs) promotes enhanced wave-matter interaction and offers approaches to high-sensitivity devices. Elastic waves can carry complex polarizations and thus differ from electromagnetic waves and other scalar mechanical waves in the formation of BICs, which is yet to be ...

Engineering with Bound States in the Continuum

Optics and Photonics News, 2020
Identified nearly a century ago by early workers in quantum mechanics, bound states can dramatically reduce radiation from optical resonators, opening up new application prospects in nanophotonics.
