Patent ID: 11156816

Abstract:
A reflective spatial light modulator includes a perovskite-type electro-optic crystal having a relative permittivity of 1,000 or higher and including an input surface to which the input light is input and a rear surface which faces the input surface; a light input and output unit disposed on the input surface of the electro-optic crystal and including a first electrode through which the input light is transmitted; a light reflecting unit including a pixel electrode portion including a plurality of second electrodes and an adhesion layer fixing the pixel electrode portion to the rear surface, is disposed on the rear surface of the electro-optic crystal, and reflects the input light toward the input and output unit; and a drive circuit for applying an electric field between the first electrode and the plurality of second electrodes. The adhesion layer includes a dielectric material in a cured material of a non-conducting adhesive material.
