Claim 2:
3. A structure comprising:
a substrate;
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 first waveguide core having a first longitudinal axis, the second waveguide core having a second longitudinal axis, 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, the first waveguide core having an end surface; and
a semiconductor laser positioned adjacent to the end surface of the first waveguide core, the semiconductor laser configured to provide light in a mode propagation direction toward the edge coupler.
