Planar chiral metasurfaces with maximal and tunable chiroptical response driven by bound states in the continuum

Here, the authors employ the physics of chiral bound states in the continuum and suggest planar chiral metasurfaces with simultaneous ultrahigh quality factor and near-perfect circular dichroism in both linear regime and nonlinear regime.
