NANOPHOTONIC RADIATOR USING GRID STRUCTURE FOR APPLICATION TO PHOTONIC PHASED-ARRAY ANTENNA

Title:

NANOPHOTONIC RADIATOR USING GRID STRUCTURE FOR APPLICATION TO PHOTONIC PHASED-ARRAY ANTENNA

Document Type and Number:

WIPO Patent Application WO/2017/086524

Kind Code:

A1

Abstract:

An optical radiator element constituting a photonic phased-array antenna and comprising: optical waveguides comprising a waveguide cladding and a waveguide core using a semiconductor material; and grids periodically formed at the upper or lower part of the optical waveguides, wherein the optical radiator element receives input light waves in one direction of the optical waveguides and grids and radiates output light waves to a space by using scattering from the grids.
