Claim 16:
17. A method comprising:
forming a first chip region of a photonics chip, wherein the first chip region includes a first waveguide core having a first tapered section; and
forming a second chip region of the photonics chip that adjoins the first chip region of the photonics chip along a first boundary, wherein the second chip region includes a second waveguide core having a second tapered section positioned across the first boundary from the first tapered section, the first tapered section has a first width dimension that increases with increasing distance from the first boundary and, the second tapered section has a second width dimension that increases with increasing distance from the first 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 first boundary.
