Abstract:
Optical/plasmonic metamaterials composed of artificial structures have attracted a huge number of interests due to their extraordinary optical properties, such as negative refractive index, optical invisibility, etc. Their single layer configuration, optical metasurfaces, enable abrupt changes to the properties of electromagnetic wave like phase, amplitude as well as polarization within a subwavelength spatial region, which is promising for the development of flat optics systems. In this presentation, I will talk about the intriguing light control through flat optical metasurfaces, which enables feasible applications of versatile polarization generations, high efficiency metalens with multi-functionality, and achromatic metasurface devices. By incorporating metasurfaces with active materials/systems, one can dynamically control the optical properties of metasurface devices on demand like beam steering, and tunable polarization conversion.
