Abstract
Various polarization rotator splitter (PRS) configurations are disclosed. In an example embodiment, a system includes a PRS that includes a silicon nitride (SiN) rib waveguide core that includes a rib and a ridge that extends vertically above the rib, the SiN rib waveguide core having a total height hfrom a bottom of the rib to a top of the ridge, a rib height hfrom the bottom of the rib to a top of the rib, a rib width w, and a top width wof the ridge. The rib width wvaries along at least a portion of a length of the SiN rib waveguide core.
