摘要
An optical coupling includes a planar tapered waveguide coupling element having a first end opposite a second end, a tapered waveguide positioned within a planar substrate, the tapered waveguide comprising a waveguide diameter that is larger at the first end than at the second end. An optical pathway is disposed within the tapered waveguide and extends between the first end and the second end. The tapered waveguide is tapered from the first end to the second end such that the waveguide diameter transitions a light beam traveling along the optical pathway from a first beam size at the first end to a second beam size at the second end.
