Claim 0:
1. A structure comprising:
a substrate; and
an edge coupler including a first waveguide core and a second waveguide core, the first waveguide core positioned in a vertical direction between the second waveguide core and the substrate, the second waveguide core including a first section and a second section, the first section of the second waveguide core having an end surface that terminates the second waveguide core and a width dimension that increases with increasing distance from the end surface, the first waveguide core having a first longitudinal axis, the second waveguide core having a second longitudinal axis, the first section of the second waveguide core positioned along the second longitudinal axis between the second section and the end surface of the second waveguide core, and the second longitudinal axis of the second waveguide core slanted at a first angle relative to the first longitudinal axis of the first waveguide core,
wherein the second section of the second waveguide core is a bend that terminates the second waveguide core adjacent to the end surface of the second waveguide core.
