WebSep 8, 2024 · We used the physics of chiral quasi-bound states in the continuum to demonstrate the efficient and controllable emission of circularly polarized light from resonant metasurfaces. WebWe reveal that optical chirality at the nanoscale can be boosted dramatically by bound states in the continuum (BIC). We predict the enhancement of chiroptical signals from nanostructures supporting quasi-BICs in mid-IR with a record-high efficiency. © 2024 The Author (s) PDF Article More Like This

Web1 day ago · Recently, there has been increasing interest in bound states in the continuum (BIC) because of its high Q-factor. As a representative class of odd optical resonance modes, the reflection-type BIC has a peak of reflectance, which provides a potential possibility to simultaneously meet the two conditions of greatly enhancing the GH shift … WebFeb 17, 2024 · Quasi-bound states in the continuum (QBICs) are Fano resonant states with long optical lifetimes controlled by symmetry-breaking perturbations. While … WebMay 9, 2014 · In chiral quantum systems there appear zero-energy states in which the wave function has finite amplitude only in one of the subsystems defined by the chiral symmetry. When the system is coupled to leads with a continuum energy band, part of these states remain bound. green licorice near me
