Abstract

The invention discloses an optical assembly for being vertically coupled with a photoelectric transceiving array and a manufacturing method, relating to the field of optical fiber communication. The optical assembly comprises an optical signal transmission device and a reflecting prism, wherein the optical signal transmission device is a multi-core optical fiber array or an array waveguide grating chip; the reflecting prism is a right trapezoid prism or a right triangle prism; the optical signal transmission device is connected with the reflecting prism through an adhesive. Rotation of a light path is realized through the reflecting prism, so that the output end face of the array waveguide grating chip or the output end face of the optical fiber array can be avoided, and the problem that the optical fiber is broken and the ground optical fiber in the later using stage is easily damaged and cannot be used when the optical fiber is ground is solved. According to the optical assembly, large-scaled production is easy and the yield is relatively high. The vertical coupling efficiency between the optical assembly and the photoelectric transceiving array can be effectively improved.

Description

technical field [0001] The invention relates to the field of optical fiber communication, in particular to an optical component for vertical coupling with a photoelectric transceiver array and a manufacturing method. Background technique [0002] With the development of optical transmission research, wavelength division multiplexing technology has become an effective means to increase the capacity of communication information. Wavelength division multiplexing refers to the transmission of multiple wavelengths into the same waveguide or optical fiber of the optical line.
