Abstract
Disclosed are an optical image modulator, an optical apparatus including the same, and methods of manufacturing and operating the optical image modulator. The optical image modulator includes a light amount increasing unit increasing the amount of forward light emission of an electric-optical unit. The light amount increasing unit includes a first reflector reflecting light, which travels from the inside of the electric-optical unit toward the optical-electric unit, to the electric-optical unit. The light amount increasing unit may further include a second light reflector reflecting light, which passes through the optical-electric unit without optical-electric conversion, to the optical-electric unit.
