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 having a plurality of side-by-side guide grooves and a plurality of first coupling parts formed on the cover plate, the bare fiber segments of the optical fiber being arranged in corresponding guide grooves, cross-sectional shapes of the guide grooves being one of U-shaped or V-shaped;
a lens installed on the guide grooves of the cover plate, the lens being connected to and directly in contact with the bare fiber segments of the optical fiber, the lens being one of through lens, a refractive lens or a reflective lens; and
a silicon chip having lines and a plurality of second coupling parts formed on the silicon chip, the optical fiber being fixed between the silicon chip and the cover plate with the first coupling parts respectively coupled with the second coupling parts, the lines being for receiving light signals output from the lens;
wherein the lens is further formed with a mounting convex portion shaped to match a shape of the plurality of side-by-side guide grooves, and the lens is set on the plurality of guide grooves by having the mounting convex portion coupled with the guide grooves.
