Structures including a grating coupler and methods of forming a structure that includes a grating coupler. The grating coupler includes segments that are spaced along a longitudinal axis. Each segment is inclined relative to the longitudinal axis. Each segment includes a first curved section having a first curvature and a second curved section having a second curvature that is inverted relative to the first curvature.

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.

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.
