Abstract
Structures for a polarization splitter and methods of fabricating a structure for a polarization splitter. First and second waveguide cores of the polarization splitter are located adjacent to each other in a coupling region. A third waveguide core is located over the second waveguide core in the coupling region. The third waveguide core is composed of a material having a variable refractive index.
