Photoelectric conversion device

摘要

A photoelectric conversion device includes an optical fiber, a molded portion covering an end portion and an end face of the optical fiber, the molded portion including a transparent resin transparent to light inputted and outputted through the optical fiber and a light input/output surface perpendicular to an optical axis of the optical fiber, electric wirings oppositely formed on the light input/output surface of the molded portion so as to sandwich a light input/output portion through which the light inputted and outputted through the optical fiber passes, and an optical device mounted on the electric wirings so as to stride over the light input/output portion. The optical device includes a surface light-emitting element or a surface light-receiving element optically coupled to the optical fiber through the molded portion.

1. A photoelectric conversion device, comprising:
an optical fiber comprising an optical fiber strand having a cladding formed around a core and an outer peripheral resin-made cover layer formed around the entire circumferential surface of the optical fiber strand; a solid uniform monolithic end cap configured to conform to a shape complementary the shape of an end of the optical fiber along the entire circumference of the optical fiber along a portion of the longitudinal surface extending from an end face and the end face of the optical fiber, the solid uniform monolithic end cap comprising a transparent resin transparent to light inputted and outputted through the optical fiber and a light input/output surface perpendicular to an optical axis of the optical fiber, a distance from the end face of the optical fiber to the light input/output surface being not less than 10 μm and not more than 200 μm, the resin-made cover layer being formed around the optical fiber strand at least along an entire length of the solid uniform monolithic end cap-covered area in a longitudinal direction of the optical fiber strand; electric wirings oppositely formed on the light input/output surface of the solid uniform monolithic end cap so as to sandwich a light input/output portion through which the light inputted and outputted through the optical fiber passes; and an optical device mounted on the electric wirings so as to stride over the light input/output portion, the optical device comprising a surface light-emitting element or a surface light-receiving element optically coupled to the optical fiber through the solid uniform monolithic end cap.
