Abstract:
In an example, a photonic system includes a Si PIC-based polarization splitter rotator (PSR) that includes first and second SiN waveguides formed in a first layer of a Si PIC, each of the first and second SiN waveguides having a coupler portion. The PSR also includes a Si waveguide formed in a second layer of the Si PIC above or below the first layer. The Si waveguide includes a first tapered end near the coupler portion of the first SiN waveguide and adiabatically coupled to the coupler portion of the first SiN waveguide, a second tapered end near the coupler portion of the second SiN waveguide and adiabatically coupled to the coupler portion of the second SiN waveguide, and a first s-bend between the first and second tapered ends that cooperates with the first SiN waveguide to form a polarization rotator for light propagating in the first SiN waveguide.

Claim (Index 18):
The photonic system of  claim 17 , wherein the polarization rotator comprises:\n an s-bend formed in the Si waveguide between the first tapered end and the second tapered end; and a portion of the first SiN waveguide that overlaps the s-bend in a light propagation direction of the first SiN waveguide, the portion of the first SiN waveguide optically coupled to the first output of the polarization rotator .
