    Abstract: Structures for a polarization rotator and methods of forming a structure for a polarization rotator. The structure comprises a first waveguide core having a first section, a second section, a first terminating end, and a second terminating end opposite to the first terminating end. The first and second sections of the first waveguide core are arranged between the first terminating end and the second terminating end. The structure further comprises a second waveguide core including a first tapered section having a first overlapping arrangement with the first section of the first waveguide core and a second tapered section having a second overlapping arrangement with the second section of the first waveguide core. The first waveguide core comprises a first material, and the second waveguide core comprises a second material different from the first material.

    Abstract: Photonics structures including a slotted waveguide and methods of fabricating such photonics structures. The photonics structure includes a slotted waveguide having a first waveguide core and a second waveguide core laterally positioned adjacent to the first waveguide core. The first waveguide core is separated from the second waveguide core by a slot. The photonics structure further includes a metamaterial structure having a plurality of elements separated by a plurality of gaps and a dielectric material in the plurality of gaps. The metamaterial structure and the slot of the slotted waveguide are positioned with an overlapping arrangement.
