A second part of the packaging comprises: second waveguide cores, each having a same second height; and one or more second alignment structures complementarily shaped with respect to the one or more first alignment structures, and wherein, the first part structured such that said inner region is recessed with respect to the outer region, to enable: the second waveguide cores to contact the first waveguide cores; and the one or more second alignment structures to respectively receive, at least partly, the one or more first alignment structures.
