Abstract
Systems and methods for optical control of radar antenna beam steering are described. An apparatus includes: a feeder waveguide; and a waveguide array electromagnetically coupled to said feeder waveguide, said waveguide array including: a plurality arms, each of said plurality of arms including: a plasma induced modulator having a transmission coefficient that is .ltoreq.1, said plasma induced modulator including: a rib waveguide electromagnetically coupled to said feeder waveguide. The systems and methods provide advatages in that optical beam steering is achieved with a lightweight inexpensive apparatus.
