    摘要： 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.

    摘要： An optical modulator that performs wide bandwidth optical modulation by using multiple Fabry-Perot resonant modes, and an apparatus for capturing a three-dimensional image including the optical modulator are provided. The optical modulator may include: a substrate; a first contact layer disposed on the substrate; a bottom distributed Bragg reflective (DBR) layer disposed on the first contact layer; an active layer disposed on the bottom DBR layer and includes a multiple quantum well layer; a top DBR layer disposed on the active layer; a cavity layer disposed in the top DBR layer; and a second contact layer disposed on the top DBR layer. Since the optical modulator achieves both a high contrast ratio and a wide bandwidth by using two or more Fabry-Perot resonant modes, the optical modulator may show a stable performance even when a resonant wavelength is changed during manufacture or due to an external environment such as temperature.
