摘要： An optical modulator, methods of manufacturing and operating the same, and an optical apparatus including the optical modulator are disclosed. The optical modulator includes an electro-optical converter and an optical-electric converter, stacked perpendicular to a substrate, and a gate transistor. The gate transistor gates a signal transmitted to the electro-optical converter from the optical-electric converter and allows charges generated in the optical-electric converter and charges remaining in the electro-optical converter to flow while bypassing the electro-optical converter when gating ON is performed.

摘要： An optoelectronic shutter, a method of operating the same, and an optical apparatus including the optoelectronic shutter are provided. The optoelectronic shutter includes a phototransistor which generates an output signal from incident input light and a light emitting diode serially connected to the phototransistor. The light emitting diode outputs output light according to the output signal, and the output signal is gain-modulated according to a modulation of a current gain of the phototransistor.

摘要： 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.
