Nearly perfect graphene chiral absorber based on chiral quasi bound states in the continuum
Chirality in photonics, particularly in absorption, has great potential for applications but remains less explored compared to scattering properties like reflection and transmission. By integrating graphene with chiral quasi-BICs from symmetry-broken bilayer photonic crystals (BPhCs), we propose a d...

| Summary: | Chirality in photonics, particularly in absorption, has great potential for applications but remains less explored compared to scattering properties like reflection and transmission. By integrating graphene with chiral quasi-BICs from symmetry-broken bilayer photonic crystals (BPhCs), we propose a design achieving near-unity circular dichroism and enhanced chiral absorption. This innovative chiral graphene absorber opens new possibilities for optical sensors, photodetectors, and energy-harvesting devices with advanced functionalities. |
