Structuring the local handedness of synthetic chiral light: global chirality versus polarization of chirality

Abstract Synthetic chiral light enables ultrafast and highly efficient imaging of molecular chirality. Unlike standard circularly polarized light, the handedness synthetic does not rely on spatial structure field: it is encoded locally , in trajectory that tip electric-field vector draws time, at each point space. both globally [Ayuso et al, <i>Nat Photon<i> 13 866 (2019)] allows us to selectively quench nonlinear response a selected enantiomer while maximizing its mirror twin level total signal intensities. exhibits <i>polarization chirality<i> Commun<i> 12 3951 (2021)] realize version Young's double-slit experiment leads enantio-sensitive bending. Here we connect these new concepts, show how one can local global space create optical fields which be chirality polarized. Using state-of-the-art computational modeling, properties are imprinted molecules, creating exciting opportunities for ultrafast, all-optical chirality.
