Abstract

An optically tunable metamaterial unit cell is provided for photonic switching. The cell is optically tunable and includes a dielectric substrate with upper and lower surfaces. The cell further includes arrays of metamaterial elements and a layer of photo-capacitive material. The arrays are disposed the upper surface of the dielectric substrate. The metamaterial is capable of reflecting electromagnetic radiation. The layer of photo-capacitive material overlaps the arrays of metamaterial elements. The photo-capacitive material is optically tunable.
