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 20):
The photonic system of  claim 14 , further comprising:\n a first wavelength division demultiplexer (WDM demux) optically coupled to the polarization splitter, wherein the first WDM demux includes a plurality of outputs and an input and wherein the input of the first WDM demux is optically coupled to the first output of the polarization splitter; and a second WDM demux optically coupled to the TM mode filter, wherein the second WDM demux includes a plurality of outputs and an input and wherein the input of the second WDM demux is optically coupled to an output of the TM mode filter.
