Structures for an optical component of a photonics chip and methods of forming a structure for an optical component of a photonics chip. The structure includes a slotted waveguide component having a first and second waveguide cores over a dielectric layer. The first waveguide core separated from the second waveguide core by a slot. The structure further includes a third waveguide core over the dielectric layer. The third waveguide core is positioned in a different level relative to the dielectric layer than the slotted waveguide component, and the third waveguide core and the first slot have an overlapping arrangement.
