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.
