Abstract:
1. An optical assembly, comprising: a waveguide assembly, said waveguide assembly in turn comprising a core layer, a lower cladding layer, an upper cladding layer, and at least one male waveguide core fiducial formed in said core layer, said core layer being positioned between said lower cladding layer and said upper cladding layer, said core layer and said at least one male waveguide core fiducial being formed in a predetermined relationship with said upper and lower cladding layers, said at least one male waveguide core fiducial not extending above or below said core layer; and an optical coupling element, said optical coupling element in turn comprising an optical element having at least one female alignment feature associated therewith, said at least one female alignment feature being mated with said at least one male waveguide core fiducial to accurately position said optical element with respect to said core in an X-Y plane.
