Abstract
A control device is provided for photonic switching. The device includes an optically tunable metamaterial unit cell. This structure includes a dielectric substrate; at least two arrays of metamaterial elements located on the top surface thereof, the metamaterial being capable of reflecting electromagnetic radiation, and a layer of photo-capacitive material overlapping the at least two arrays of metamaterial elements, the photo-capacitance of the photo-capacitive material being optically tunable; and a reflectarray or phased array system containing the unit cell.
