Abstract
Structures for a polarizer and methods of fabricating a structure for a polarizer. A waveguide crossing includes a first arm and a second arm. A waveguide loop couples the first arm of the waveguide crossing to the second arm of the waveguide crossing. The waveguide crossing and the waveguide loop provide a structure for the polarizer.
