Chiral Nanophotonics
Abstract
The PI and his group opened new directions of research in chiral nanophotonics by investigating theoretically and experimentally the interaction of chiral light (circularly and elliptically polarized) with both individual and ensembles, known as metasurfaces, of chiral nanoparticles/nanostructures, engineered using advanced nanofabrication techniques and measured with broadband (visible to near infrared) far field and nearfield optical techniques. This includes: an in-depth study of chiral holograms and their ability to project vastly different images depending on the chirality of light; multispectral chiral imaging with a metalens; ultracompact chiral spectrometer functionalities with metalenses; the demonstration of giant intrinsic chirooptical activity in planar dielectric nanostructures orders of magnitude higher than previously reported; metasurface polarization optics that enables to achieve different functionalities depending on the polarization of incident light; arbitrary spin-to-orbital angular momentum conversion in metasurfaces as a new route to creating structured light.
