ABSTRACT:
To provide a optical element array in which a plurality of optical elements can be monolithically integrated, and each of the optical elements can be independently driven. A optical element array in accordance with the present invention includes a plurality of optical elements having light emitting sections formed above a substrate and photodetecting sections formed above the light emitting sections; and an element isolation section that is formed between the optical elements, for electrically isolating each of the optical element from the other, wherein the substrate is dielectric or semi-dielectric, the light emitting section includes a first semiconductor layer, an active layer, and a second semiconductor layer, the photodetecting section includes a first contact layer, a photoabsorption layer, and a second contact layer, the optical element has a first electrode that is electrically connected to the first semiconductor layer, and a second electrode that is electrically connected to the second semiconductor layer, the first electrodes are electrically isolated one from the other between the optical elements, and the second electrodes define a common electrode for driving the light emitting section and the photodetecting section.
