Chiral optical responses are manifested by different responses to left circularly polarized (LCP) and right circularly polarized (RCP) light. Such chiral objects can be obtained by breaking the mirror symmetries of the objects. However, the chiral responses in natural materials are typically weak. To overcome this challenge, various resonant nanostructures have been widely studied to substantially enhance the chiral responses. Our group has recently conducted detailed studies on chiral light emission from achiral materials (perovskite emitters and colloidal quantum dots) using photonic resonances in chiral metasurfaces and cavities. In this talk, we discuss two related studies from our group: (i) chiral emission from perovskite metasurfaces and cavities, and (ii) chiral emission from quantum dot-coated metasurfaces. In both cases, we demonstrate a large degree of circular polarization (DCP) of luminescence from emitter-integrated nanophotonic structures.
