报告摘要:
Metasurfaces are ultra-thin metamaterials composed by planar meta-atoms arranged in specific macroscopic orders, which exhibit strong capabilities to control light [1-2]. In this Colloquium, I will present a brief overview on the historical development of this fast-developing research field, focusing particularly on our recent efforts in employing metasurfaces to control light in various aspects. Specifically, I will describe how to design meta-couplers to efficiently squeeze propagating light into on-chip photonic devices [3-4], propose a new mechanism to realize dynamical multi-mode modulation with one single dielectric metasurface [5], and discuss the role of “coupling” in dictating the optical properties of metasurfaces [6].
