Abstract:
1. An optical assembly, comprising: a waveguide assembly, said waveguide assembly in turn comprising a core, a cladding portion, and at least one waveguide core fiducial, said at least one waveguide core fiducial and said core being lithographically formed substantially simultaneously in a substantially coplanar layer, said core and said at least one waveguide core fiducial being formed in a predetermined relationship with said cladding portion; an optical coupling element, said optical coupling element in turn comprising an optical element and at least one alignment feature associated with said optical element, said at least one alignment feature being mated with said at least one waveguide core fiducial to accurately position said optical element with respect to said core in an X-Y plane; and at least a second waveguide core fiducial and at least a second corresponding alignment feature, such that there are at least two waveguide core fiducials and at least two alignment features mated together; wherein said optical coupling element comprises a mechanical transfer (MT) ferrule.
