Abstract
Structures for a polarizer and methods of fabricating a structure for a polarizer. A first waveguide core has a first tapered section, a second tapered section, and a section positioned along a longitudinal axis between the first tapered section and the second tapered section. The first tapered section and the second tapered section each narrow in a direction along the longitudinal axis toward the section. A second waveguide core has a first terminating end, a second terminating end, and a section that is arranged between the first and second terminating ends. The section of the second waveguide core is positioned either over or below the section of the first waveguide core.
