Abstract:
1. An optical transmission assembly, comprising: an upper cladding; a lower cladding; a specified width core formed between the upper cladding and the lower cladding; a surface light emitting device mounted on an upper surface of the upper cladding, a light emitting surface of the surface light emitting device facing the core; a reflective surface formed at a position in the core facing the light emitting surface of the surface light emitting device, and inclined in a longitudinal direction of the core; a shift area formed in which a beam from the light emitting surface of the surface light emitting device is relatively shifted from the reflective surface in a width direction of the core; and a light receiving device mounted on a lower surface of the lower cladding, a light receiving surface of the light receiving device facing the light emitting surface of the surface light emitting device through the shift area, wherein the beam from the light emitting surface of the surface light emitting device that passed through the shift area is transmitted through the lower cladding and received at the light receiving device.
