Abstract: Structures for a wavelength-division multiplexing filter and methods of forming a structure for a wavelength-division multiplexing filter. The structure includes a first slab having a first perimeter, a first waveguide core coupled to the first slab, and a plurality of second waveguide cores coupled to the first slab. A second slab is positioned to overlap with the first slab. The second slab includes a second perimeter and openings that are distributed inside the second perimeter. The openings of the second slab penetrate through the second slab.

Abstract: Structures for an optical power splitter and methods of forming a structure for an optical power splitter. A splitter body defines a multimode interference region of the optical power splitter. A first side element positioned adjacent to a first side surface of the splitter body, and a second side element positioned adjacent to a second side surface of the splitter body.
