Abstract
An optical transmission assembly consists of 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 by which a beam from the light emitting surface of the surface light emitting device and the reflective surface are shifted in a width direction of the core relative to each other; 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.
