High precision photonic alignment device

A method for manufacturing an alignment device, the method comprising:

• obtaining an input position array by measuring a position of a core of each of a plurality of optical fibers secured to respective coupling elements of a coupling element array, wherein, each of the plurality of optical fibers is associated with a respective input of a plurality of inputs of the alignment device such that the input position array indicates relative positions of the plurality of inputs of the alignment device;
• obtaining an output position array based at least in part on a plurality of target locations of a receiving device;
• determining one or more waveguide paths, each waveguide path configured to provide an optical path between one or more respective input positions of the input position array to one or more respective output positions of the output position array;
• and
• fabricating, based on the input position array, the output position array, and the one or more waveguide paths, the alignment device, wherein the alignment device comprises a substrate comprising a plurality of inputs at respective input positions corresponding to the input position array, a plurality of outputs at respective output positions corresponding to the output position array, and one or more waveguides corresponding to the one or more waveguide paths.
