Abstract:
Metamaterials, derived from transformation optics or negative refraction law, have been receiving intensive attention. Exciting progress has been made to pave the way from fundamental physics to real-world devices, exhibiting unprecedented light phenomena, such as cloaking, super-resolution, focusing, redistribution of photon momentum, etc. In this talk, we will present an alternative look into the realm of non-metamaterials, and see whether they can perform as equally well as, if not better than, the metamaterial counterpart. In particularly, we will introduce meta-surface and its implication of generating metalight, in order to miniaturize the bulky metamaterials. The ultrathin metasurface becomes an unprecedented tool to manipulate the light in just few hundreds of nanometer thickness, and metalight, as a consequence, has demonstrated its intrinsic capability in micromanipulation of particles.
