报告摘要：
Device miniaturization and system integration are two continuing trends. However, further reduction in the thickness of the optical elements is hindered by the design theory. Optical metasurfaces consisting of nanostructures can control light propagation in a desirable manner, providing new opportunities to develop ultrathin optical devices with unusual functionalities. In this talk, I am going to review the current progress in optical metasurfaces and talk our recent work in metasurface based ultrathin optical devices (e.g., metalenses, holograms, optical vortex beams, multifunctional devices, and 3D polarization manipulation) and their applications in imaging, displays, encryption, and detection.
