Abstract: The problem addressed by the present invention is to provide: an optical receptacle that can be easily positioned with a photoelectric converter having a light-emitting element and a detection element. In order to solve the problem, an optical receptacle is provided, said optical receptacle being positioned between a light transmission medium and a photoelectric converter having a substrate, a photoelectric conversion element and a detection element, and the purpose of the optical receptacle being to optically couple the photoelectric conversion element and the end surface of the light transmission medium. The optical receptacle comprises a filter, a holding member for holding the filter, and a receptacle body. In the optical receptacle the holding member and the receptacle body are separate bodies, and the filter reflects towards the detection element side, as monitor light, part of the light emitted from the photoelectric conversion element, and transmits the remainder as signal light.

Abstract: This optical receptacle is provided with: a first optical surface; a second optical surface; a first recess; a second recess; an inclined surface; insertion holes; through holes; and reference parts. The second optical surface and the inclined surface face each other at inside surfaces of the first recess. The inclined surface is inclined so as to extend away from the second optical surface as the inclined surface approaches an opening of the first recess. First openings which are open at the inclined surface and second openings which are open at an inside surface of the second recess are provided at both ends of the linear insertion holes. The thorough holes face the second openings on the central axes of the insertion holes. The reference parts are provided to the surface at the side at which the first recess and the second recess are open.

Abstract: This optical receptacle is provided with: an optical receptacle main body provided with a plurality of first optical surfaces and a plurality of second optical surfaces; and an optical filter. Light emitted from a photoelectric conversion element becomes incident on the first optical surfaces. The second optical surfaces allow light which becomes incident on the first optical surfaces, and passes through the inside, to exit towards an end surface of an optical transmission body. The optical filter is disposed so as to face some of the plurality of second optical surfaces, and attenuates the amount of light from the facing second optical surfaces. The optical filter is disposed with respect to at least one of the one or more second optical surfaces facing the optical filter, such that positional deviation between the first optical surfaces and the second optical surfaces is taken into consideration.

Abstract: This optical receptacle has a first optical surface, a reflection surface, a second optical surface, a light separation part, and a third optical surface. On the first optical surface, light from a photoelectric conversion element is incident. The reflection surface reflects the light incident on the first optical surface. The second optical surface allows the light reflected by the reflection surface to be emitted toward an end surface of an optical transmission body. The light separation part separates the light reflected by the reflection surface, into monitor light and signal light. The third optical surface allows the monitor light to be emitted toward a detection element. The light separation part includes divided reflection surfaces and divided transmission surfaces. At least one of the divided transmission surfaces includes one or more widened portions each having a width larger than those of the other divided transmission surfaces.

Abstract: An optical receptacle includes: an optical receptacle body; two supporters which are connected to a respective end of the optical receptacle body, wherein each supporter is connected to one end of the optical receptacle body at a central portion of the respective supporter, and the two supporters face each other with a space therebetween; and four adhesive reservoirs which are disposed at respective four corners of the optical receptacle in plan view, wherein each of the adhesive reservoirs is a through hole or a recess, and the through hole or the recess is surrounded circumferentially by the supporter. The optical receptacle body and the two supporters together have a plane symmetrical shape with respect to a plane parallel to an optical axis of the light emitted from each of the second optical surfaces. The four adhesive reservoirs are disposed plane symmetrically with respect to the plane.
