Abstract
Structures with waveguide cores in multiple levels and methods of fabricating a structure that includes waveguide cores in multiple levels. The structure includes a first waveguide core and a second waveguide core positioned in a different level than the first waveguide core. The first waveguide core includes a longitudinal axis and a plurality of segments having a spaced arrangement along the longitudinal axis. The second waveguide core is aligned to extend across the plurality of segments of the first waveguide core.
