Abstract
Structures for polarization filtering and methods of forming a structure for polarization filtering. A waveguiding structure has a first waveguide core region including a first plurality of bends, a second waveguide core region including a second plurality of bends laterally spaced from the first plurality of bends by a gap, and a third waveguide core region including a third plurality of bends positioned beneath the gap. The first waveguide core region and the second waveguide core region contain a first material. The third waveguide core region contains a second material that differs in composition from the first material.
