Abstract: Photonics chip structures including a reflector and methods of forming such structures. The photonics chip structure comprises a first waveguide core, a second waveguide core adjacent to the first waveguide core, and a reflector including a plurality of metal contacts over a portion of the first waveguide core. The second waveguide core is configured to couple light to the first waveguide core, and the metal contacts are configured to reflect the light.
