Patent ID: 8436370

Claim:
An optical modulator comprising: an optical-electric (O-E) conversion element that converts an optical image into signals through a photoelectric effect; an electric-optical (E-O) conversion element that emits light using the signals from the O-E conversion element; a trench having a predetermined depth from at least a surface of the optical modulator to block or reduce electric interferences between pixels when the signals are transferred from the O-E conversion element to the E-O conversion element; and a transferring element which transfers the current signals from the O-E conversion element to the E-O conversion element, and is disposed between the O-E conversion element and the E-O conversion element, wherein a first transparent electrode is formed on an optical image incident surface of the optical modulator, a second transparent electrode is formed on an optical image output surface of the optical modulator, and an internal electrode is formed between the O-E conversion element and the E-O conversion element.
