Abstract: A photonic radiator device forming a photonic phased array antenna includes a light waveguide including a waveguide clad and a waveguide core using a semiconductor material, and a grating periodically formed an upper or lower part of the light waveguide. The photonic radiator device receives an input light wave in a direction of the grating and the light waveguide and radiates an output light wave to a space by using scattering from the grating.
