Claim Text:
1. An optical coupling element comprising: a main body comprising: a first optical surface; a second optical surface perpendicular to the first optical surface; and a reflective surface tilted relative to the first and second optical surfaces, wherein the main body defines positioning holes adjacent to the first optical surface and avoiding grooves in sidewalls of the positioning holes and communicated with the positioning holes; at least one first converging lens formed on the first optical surface; and at least one second converging lens formed on the second optical surface and corresponding to the first converging lens one by one, the first converging lens, the reflective surface, and the second converging lens cooperatively forming an optical path; wherein each positioning hole are communicated with two of the avoiding grooves and each two avoiding grooves are symmetrical about a center of the positioning hole.
