Abstract
Provided is an optical modulator having pixelization patterns. The optical modulator includes an optical-electric (O-E) conversion element converting input optical images to current signals using the photoelectric effect, and an electric-optical (E-O) conversion element that emits light using the current signals transferred from the O-E conversion element. Trenches are formed from at least a surface of the optical modulator to a predetermined depth in the optical modulator so as to block or reduce electrical interference between pixels when the electric signals are transferred from the O-E conversion element to the E-O conversion element.
