Abstract
Embodiments relate to a photonic component having a metasurface. The metasurface includes a substrate with a thin-layer of meta-atoms disposed thereon. The photonic component includes a waveguide having a top surface, wherein the metasurface is disposed on at least a portion of the top surface such that the meta-atoms form an array on the top surface. The photonic component includes a sandwich nano-bar antenna formed in or on the metasurface.
