ABSTRACT:
A vertical-to-surface transmission electrophotonic device in a structure having a first distributed Bragg reflector of a first conductivity type, a first spacer layer of the first conductivity type, an active layer, a second spacer layer of a second conductivity type opposite to the first conductivity type, and a second distributed Bragg reflector of the second conductivity type, all of which are formed on a substrate to constitute a cavity in a direction perpendicular to a formation surface, characterized in that one layer of said first distributed Bragg reflector is locally thickened to constitute a double cavity, and that a light-emitting portion of a single-cavity structure and a light-receiving portion of a double-cavity structure are formed on said single substrate.
