Claim 0:
1. A structure comprising:
a photonics chip including a first chip region, a second chip region, a first waveguide core in the first chip region, and a second waveguide core in the second chip region, the first chip region adjoining the second chip region along a boundary, the first waveguide core including a first tapered section, the second waveguide core including a second tapered section positioned across the boundary from the first tapered section, the first tapered section having a first width dimension that increases with increasing distance from the boundary, and the second tapered section having a second width dimension that increases with increasing distance from the boundary,
wherein the first tapered section is laterally offset relative to the second tapered section, the first tapered section has a first longitudinal axis, the second tapered section has a second longitudinal axis that is aligned parallel to the first longitudinal axis, and the first tapered section abuts the second tapered section at the boundary.
