Light-emitting diode of edge-emitting type, light-receiving device of lateral-surface-receiving type, and arrayed light source

摘要

A semiconductor device includes a semiconductor substrate, and a plurality of semiconductor layers formed on the semiconductor substrate and forming a concave lateral surface, the semiconductor layers including an active layer for either emitting light or receiving light, wherein the concave lateral surface is used as either a light-emitting surface or a light-receiving surface.
