Abstract
A light modulator includes a perovskite-type electro-optic crystal including a first surface to which the input light is input and a second surface which faces the first surface; a first electrode which is disposed on the first surface of the electro-optic crystal and through which the input light is transmitted; a second electrode which is disposed on the second surface of the electro-optic crystal and through which the input light is transmitted; and a drive circuit for applying an electric field between the first electrode and the second electrode. The first electrode is disposed alone on the first surface. The second electrode is disposed alone on the second surface. At least one of the first electrode and the second electrode partially covers the first surface or the second surface. A propagation direction of the input light and an applying direction of the electric field are parallel to each other.
