Title
Active-matrix-addressed spatial light modulators based on the longitudinal Pockels effect in oblique-cut perovskites
Abstract
Oblique-cut layers from the perovskite crystals potassium tantalate niobate and barium titanate and from the tungsten-bronze crystal strontium barium niobate are suggested as control layers for active-matrix-addressed electro-optic spatial light modulators. Since all these materials consist of oxygen octahedra as building blocks and since they all exhibit their highest electro-optic effect in the tetragonal (4 mm) phase, a common theoretical treatment is used to determine the optimal oblique-cut angle. Preliminary experimental results on oblique-cut crystals are presented and a compact and efficient optical system for their use is proposed.
