ABSTRACT:
A self-aligned optical coupler for connecting an optical waveguide circuit with another optical waveguide circuit. Each waveguide circuit has a plug with an aligned structure. The plugs of the respective waveguide circuits are inserted into a receptacle having alignment structures. The alignment structures of the first and second plugs are mated in such a fashion with the receptacle so that there is optical alignment between the plugs so that optical signals can propagate from one waveguide to another. The structures may attain alignment through physical or visual approaches.
