Claim Text:
1. A method for connecting a stack of waveguide layers to a face of a ferrule presenting a mechanical alignment structure, the method comprising: bringing a ferrule in an alignment position; for each waveguide layer in the stack of waveguide layers, dispersing glue into one or more cavities of the mechanical alignment structure; for each waveguide layer in the stack of waveguide layers, sliding the waveguide layer into the one or more cavities of the mechanical alignment structure; inserting a comb tool in the ferrule so that the tool presses the stack of waveguide layers into the cavities; glue curing the ferrule; and adding a cover to the ferrule, wherein the mechanical alignment structure comprises mechanical alignment slots arranged in a bidirectional lattice structure.
