Abstract

different in refractive index in a single crystal material and controlling light in terms of refraction and reflection by partially controlling the spontaneous polarization direction of a crystal material, a production method thereof, and an optical component using the optical control element. The optical control element has at least two areas (10, 20) consisting of a crystal, having different refractive indexes due to different polarization directions, and contacting each other at the interface (15), and is uniform in composition over the entire two areas (10, 20) including the interface (15). A polarization direction is controlled by applying an electric field having such an electric field component that directs vector V toward a positive electric field, vector V satisfying vector V = vector Cb vector Ca, where Cb is direction vector in a polarization direction before controlling, and Ca is direction vector in a polarization direction after controlling.
