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.
Claims21
A photonic component, comprising:
- a metasurface comprising a substrate with a thin-layer of meta-atoms disposed thereon;
- and
- a waveguide having a top surface, wherein the metasurface is disposed on at least a portion of the top surface, wherein the meta-atoms form an array on the top surface, wherein the meta-atoms form sandwich nano-bar antennas;
- and
- wherein the metasurface comprises an array of meta-atoms.
A metalens, comprising:
- a metasurface comprising a substrate with a thin-layer of meta-atoms disposed thereon;
- a waveguide having a top surface, wherein the metasurface is disposed on at least a portion of the top surface, wherein the meta-atoms form a spatial arrangement on the top surface;
- and
- a sandwich nano-bar antenna formed in or on the metasurface;
- wherein the spatial arrangement of meta-atoms provide a focal length for the metalens.
A metasurface-dressed optical ring resonator, comprising:
- an optical ring comprising a plurality of waveguides;
- and
- a guided-wave driven metasurface structure disposed on at least one waveguide of the optical ring, the guided-wave driven metasurface structure comprising:
- a metasurface comprising a substrate with a thin-layer of meta-atoms disposed thereon, wherein the metasurface is disposed on at least a portion of a top surface of the at least one waveguide, wherein the meta-atoms form an array on the top surface;
- and
- a sandwich nano-bar antenna formed in or on the metasurface.
A photonic component, comprising:
- a metasurface comprising a substrate with a thin-layer of meta-atoms disposed thereon;
- and
- a waveguide having a top surface, wherein the metasurface is disposed on at least a portion of the top surface, wherein the meta-atoms are formed on the top surface, wherein the meta-atoms form sandwich nano-bar antennas.
