Abstract
An optical element includes an electro-optic crystal having an isotropic crystal which belongs to a point group m3m of a cubic system and including an input surface to which input light is input and a rear surface which is a surface on the opposite side of the input surface; a first electrode disposed on the input surface; and a second electrode disposed on the rear surface. The input surface is located along at least one axis between axes obtained by rotating two crystal axes about one remaining crystal axis used as a rotation center at a predetermined angle in three crystal axes of the electro-optic crystal. A direction of an electric field to be induced by a voltage applied to a part between the first electrode and the second electrode is set in a propagation direction of the input light.
