Abstract
An electrooptical deflector is presented. The electrooptical deflector includes a material that has a different refractive index for different polarization states and changes its refractive index in response to voltage (e.g., lithium niobate or lithium tantalite). Inside the material is a poled region that includes triangularly-shaped prisms, each of which affects the direction in which an incident light beam propagates. When a light beam of a known polarization state propagates through the material, its direction of propagation (i.e., the amount of deflection) is controlled by a voltage applied to the poled region and the size and number of the prisms in the material.
