Title:
NANOPHOTONIC RADIATOR HAVING MODULABLE GRID STRUCTURE FOR APPLICATION TO PHOTONIC PHASED-ARRAY ANTENNA
Document Type and Number:
WIPO Patent Application WO/2017/086523
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, radiates output light waves to a space by using scattering from the grids, and varies the effective refractive index of the grids through voltage application or current injection around the optical radiator element so as to control the radiation angle of the output light waves radiated to the space.
