Problems solved by technology

[0002] For the optical waveguide interconnection of different layers of backplanes and the three-dimensional complex optical waveguide interconnection structure, the 3D direct writing technology based on the microfluidic dispensing machine is used to prepare the optical waveguide circuit; During coupling transmission, it is necessary to use a high-precision adjustment frame to debug and align the signal transmission fiber with the prepared waveguide. However, this method of debugging and alignment is complicated, the production efficiency is low, and the cost is high, so it cannot be mass-produced efficiently.

Abstract

The invention relates to a waveguide optical fiber alignment coupling transmission structure, which comprises an optical waveguide plate, a hollow optical fiber, a waveguide, a guide pin and a multi-core beam-expanding lens connector; the hollow optical fiber is fixedly arranged in a pre-embedded optical fiber V-shaped groove with a solid optical fiber section facing outwards; the guide pin is fixedly arranged in a guide pin V-shaped groove; the waveguide is connected with a hollow optical fiber section of the hollow optical fiber; a cladding is also arranged on the upper plate surface of theoptical waveguide plate and covers and wraps the hollow optical fiber and the waveguide; the multi-core beam-expanding lens connector is fixedly connected with the optical waveguide plate through guide pin positioning; through the pre-embedded optical fiber V-shaped groove and the guide pin V-shaped groove which are precisely machined in the optical waveguide plate at a time, the relative positionprecision of the hollow optical fiber and the guide pin after installation is guaranteed, therefore the optical fiber alignment precision of the hollow optical fiber and the MT optical connector is guaranteed when signals of the optical waveguide plate are mutually coupled and transmitted, the debugging alignment process link is omitted, the structure and the method have the advantages of high production efficiency and low cost, and meet the mass production requirements of interconnection of optical waveguides of different layers of backboards.
