Abstract: A photonic radiator forming a photonic phased array antenna includes a light waveguide including a waveguide clad and a waveguide core using semiconductor materials, and a grating periodically formed on an upper or lower part of the light waveguide, wherein the photonic radiator receives an input light wave in a direction of the grating and the light waveguide, radiates an output light wave to a space through scattering from the grating, and varies an effective refractive index of the grating through voltage supply or current injection in the vicinity of the photonic radiator to adjust a radiation angle of the output light wave that is radiated to the space.
