Abstract
Disclosed is an array antenna which is capable of shifting a phase of light. According to one aspect of the present exemplary embodiment, an optical phase shifting array antenna includes: a receiving unit configured to distribute input light to a plurality of antenna element waveguides; a phase shifting unit configured to shift a phase of light propagated to each antenna element waveguide by applying heat to each antenna element waveguide; an output unit including a plurality of antenna elements, and configured to output the light, which is propagated to each antenna element waveguide after a phase is varied in the phase shifting unit, to each antenna element; and a base part configured to seat the receiving unit, the phase shifting unit, and the output unit.
