We demonstrate a lanthanum-modified lead zirconate titanate ceramic-based electro-optic beamsteering device that has a 3 mm × 33 mm working area. A series of resistors were made by evaporation of chromium onto the substrate to produce and control the required voltage distribution among the electrodes. A steering angle of 0.04° was obtained with an applied voltage of 700 V. Design considerations, computer simulations, and experimental results are presented.
