ABSTRACT:
A two-dimensional modulator array for modulating a plurality of light beams. The modulator array is comprised of a plurality of stacked wafer layers. Each of the wafer layers have a linear array of transversely driven Pockels modulators. The Pockels modulators are formed by placing a plurality of electrodes over a top surface of an optical material and extending the electrodes over a beveled edge of the optical material. A ground plane resides on the bottom surface of the optical material. Conductive end reflectors are associated with each of the modulator electrodes. These end reflectors reflect the light beams back through the wafer. Electrical attachments are connected to the ends of each electrode for controlling the modulation for each electrode. Thereby, separate light beams can be individually modulated.
