Nearly perfect graphene chiral absorber based on chiral quasi bound states in the continuum

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...
