Abstract
An optical coupling structure and an optical communication apparatus using the same are provided. The optical coupling structure includes a light incident portion, a light splitting portion, a first light emitting portion, and a second light emitting portion. An initial optical signal entering the optical coupling structure through the light incident portion is divided into a first beam and second beam by the light splitting portion, which includes a first reflective surface and a second reflective surface, and the slopes of the first and second reflective surfaces are both positive or both negative. The first beam is converted by the first light emitting portion into a first optical signal for transmitting to an optical transmission unit. The second beam is converted by the second light emitting portion into a second optical signal for transmitting to a photodetector.
