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 17):
The photonic system of  claim 14 , wherein:\n the polarization splitter comprises a coupler portion of a first silicon nitride (SiN) waveguide formed in a silicon (Si) photonic integrated circuit (PIC) and a first tapered end of a Si waveguide formed in the Si PIC, wherein the first tapered end of the Si waveguide is aligned in two orthogonal dimensions with the coupler portion of the first SiN waveguide; and the TM mode filter comprises a coupler portion of a second SiN waveguide formed in the Si PIC and a second tapered end of the Si waveguide, wherein the second tapered end of the Si waveguide is aligned in two orthogonal dimensions with the coupler portion of the second SiN waveguide.
