Abstract:
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.
