Claim 0:
1. An alignment structure of optical element, comprising:
an optical fiber, having a parallel fiber segment and a plurality of bare fiber segments;
a cover plate, provided with a plurality of side-by-side guide grooves and a plurality of first coupling parts, the bare fiber segments of the optical fiber being arranged in corresponding guide grooves, cross-sectional shapes of the guide grooves being at least one of U-shaped or V-shaped, and the cover plate being formed with an alignment groove located at one end of the guide grooves;
a lens, the lens being at least one of a through lens, a refractive lens or a reflective lens; and
a silicon chip, provided with lines and a plurality of second coupling parts, the lines being for receiving light signals output from the lens; when the cover plate is matched with the silicon chip, the first coupling parts and the second coupling parts being coupled and positioned with each other respectively, the lens being arranged in the alignment groove and fixed between the cover plate and the silicon chip during assembling and the optical fiber being fixed between the silicon chip and the cover plate;
wherein the lens forms a flat mounting surface, a longitudinal direction of the alignment groove is a tapered hole, the flat mounting surface has a shape matches with the shape of a bottom surface of the alignment groove and when the lens is placed in the alignment groove, the flat mounting surface accurately fits the bottom surface of the alignment groove.
