Abstract
A polarization rotator rotates a portion of light received from an input surface to an orthogonal polarization. A polarization splitter is coupled to the polarization rotator and includes a channel waveguide section that transmits the rotated portion of the light towards an output surface. The splitter also includes a splitter waveguide separated from the channel waveguide section by a dielectric gap. The splitter waveguide couples an unrotated portion of the light away from a target region of the output surface.
