Holographic Metasurface with Full-Stokes Vectorial Property
Hosted By: Thin Films Technical Group
06 July 2022 21:00 - 22:00
Eastern Time (US & Canada) (UTC - 05:00)Metasurfaces as a novel and extraordinary platform have demonstrated intriguing electromagnetic properties by tailoring the artificial structures. Since its emergence, multidimensional modulation of light is always the focus of researchers, which is expected to improve information capacity and realize dynamic optical response at different incident conditions. In this webinar hosted by the Thin Films Technical Group, Lingling Huang will present a metasurface design method to shape the amplitude; phase and polarization simultaneously by using the resonance effects and geometric phase of subwavelength lattice; and rebuild a full-Stokes vectorial holography with high precision and unlimited number of polarizations. By changing the crossed input/output polarization selections, dynamic modulations to holographic images are experimentally demonstrated, which is also available for versatile beams and patterns. With a customizable optical manipulation and large field of view, such ultrathin metasurfaces are expected to be used in dynamic display, non-mechanical dynamic scanning (Lidar), dynamic optical manipulation, and so on.
