Title: OPTICAL RECEPTACLE AND OPTICAL MODULE
Abstract:
This optical receptacle is disposed between a photoelectric conversion device, which has a light-emitting element and a detection element, and an optical transmission body, and optically couples the light-emitting element and a cross-section of the optical transmission body, the optical receptacle having: a first optical surface on which light emitted from a light-emitting element is incident; a light splitting unit which splits the light incident on the first optical surface into monitor light that travels toward the detecting element and signal light that travels toward the cross-section of the optical transmission body; a second optical surface which emits the signal light split in the light splitting unit toward the cross-section of the optical transmission body; and a third optical surface which emits the monitor light split in the light splitting unit toward the detection element. The first optical surface causes the light incident thereon to converge so that the beam waist is positioned in the optical path between the first optical surface and the second optical surface.
