This presentation will focus on nanostructured materials with responsive optical properties that can find applications in printing, sensing, signage, security documents, and displays. We will discuss our recent progresses on the development of chemical and assembly approaches for the fabrication of various nanostructured materials whose optical properties can be dynamically tuned by controlling the spatial arrangement of the nanoscale building blocks. Many novel optical materials could be developed by manipulating the diffraction, refraction, birefringence, and electronic resonances through controlling the interaction between light and the nanostructures.报告人介绍:Prof. Yadong Yin received his B.S.

内容摘要：Benefitting from the rapid development of nanotechnology, nano-scale manipulation of light in terms of its phase, amplitude, polarization and wavelength is available and opens the door to metamaterials/metasurfaces and nanophotonics. This presentation is focused on three basic problems in nanophotonics. First, focusing light into a nanoscale spot will be discussed with the theoretical prediction of its real diffraction limitation, design methods of planar metalens, experimental realization and its applications in optical super-resolution imaging and nanofabrication. Second, shaping light to reconstruct a holographic image is another hot topic including metasurface holograms and nanosieve holograms that will be presented with simulated and experimental results such as having no high-order diffraction and twin-image issues, ultra-broadband operation, large angle-of-view, high uniformity, etc. Finally, nano-structuring light with a helical wavefront related to its orbital angular momentum (OAM) provides a novel approach to realize the compact and polarization-sensitive vortex generator. The twisted focusing and continuous generation of optical OAMs will be demonstrated.
