Abstract

An optical component for vertical coupling with a photoelectric transceiver array and a manufacturing method, which relate to the field of optical fibre communications. The optical component comprises an optical signal transmission apparatus and a reflector prism (3), wherein the optical signal transmission apparatus is a multi-chip optical fibre array (1) or an array wave-guide grating chip (5), the reflector prism (3) is a right-angled trapezoid-shaped prism or a right-angled triangle-shaped prism, and the optical signal transmission apparatus is connected to the reflector prism (3) by means of an adhesive (2). Realizing optical path angle conversion by means of the reflector prism (3) can avoid destroying an output end face of the array wave-guide grating chip (5) or an output end face of the optical fibre array (1), and avoid the problems that an optical fibre break is caused when an optical fibre is polished and the polished optical fibre is too easily broken to use in later use. The optical component is easy to produce on a large scale and has a higher acceptability rate. The method can effectively improve the efficiency of vertical coupling between the optical component and the photoelectric transceiver array.
