內容摘要:
Metasurfaces, artificially designed nano-scatterers, have attracted immense attention because of their great ability to control the optical properties and wavefront at a subwavelength scale. Thus, they hold promise for various flat optical applications such as compact spectrometers and low-profile spatial light modulators. In this talk, I will firstly discuss the intriguing characteristics of optical metasurfaces for phase modulation, amplitude control, and dispersion engineering, which enable feasible applications of focusing metalens and achromatic metasurface devices. Subsequently, the presentation will shift to the scheme of tunable functionalities with dynamic metasurfaces. By incorporating metasurfaces with active materials, one can actively control the optical properties of metasurface devices at will, leading to the realization of novel low-profile optical components, including a tunable polarization converter, dynamically switchable diffraction grating, and beam steering. Finally, several approaches such as automatic inverse design, toroidal resonance modes, and plasmonic Huygens source utilized to accomplish high-performance metasurfaces will be presented and discussed.
