More Information
Summary:An apparatus is disclosed for generating electromagnetic waves such as terahertz waves. The apparatus may comprise a finger structure having a plurality of conductive lines, wherein at least two of the plurality of conductive lines is separated by photosensitive material, a plurality of detectors, and a capacitor having a plurality of conductive lines separated by a dielectric material. Light from a laser incident on the photosensitive material causes free carriers in the photosensitive material to move to a conduction band and be accelerated by a voltage across the conductive lines of the finger structure applied by the capacitor to produce the terahertz waves.
