Abstract:
1. A optical element array comprising: a plurality of optical elements having a substrate, light emitting sections formed above the 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 the optical elements from one another, 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, a second electrode that is electrically connected to the second semiconductor layer, and a third electrode that is electrically connected to the first contact layer the first electrodes are electrically isolated from one another between the optical elements, and the second electrodes define a common electrode for driving the light emitting section and the photodetecting section.
