Abstract
Structures including stacked photonics chips and methods of fabricating a structure including stacked photonics chips. The structure comprises a first chip including a first waveguide core, a ring resonator adjacent to a portion of the first waveguide core, and a first dielectric layer over the first waveguide core and the ring resonator. The first dielectric layer has a first surface. The structure further comprises a second chip including a second waveguide core and a second dielectric layer over the second waveguide core. The second dielectric layer has a second surface adjacent to the first surface of the first dielectric layer, and the second waveguide core is positioned adjacent to the ring resonator.
