Structures including a waveguide core and methods of fabricating a structure including a waveguide core. The structure comprises a substrate, a waveguide core, and a grating disposed in a vertical direction between the waveguide core and the substrate. The grating includes a first plurality of layers and a second plurality of layers that alternate in the vertical direction with the first plurality of layers. The first plurality of layers comprise a first material having a first refractive index, and the second plurality of layers comprise a second material having a second refractive index that is greater than the first refractive index.
