Abstract
In part, the disclosure relates to system. The system includes a polarization diversified wavelength demultiplexer (WDM). The polarization diversified wavelength demultiplexer includes a polarization beam splitter configured to output a first polarized signal and a second polarized signal based on an input signal; and a wavelength demultiplexer (WDM) having two inputs that are connected to the two outputs of the polarization beam splitter, and configured to output signals with a single set of outputs that carry signals of both polarizations, based on the first polarized signal from the first input and the second polarized signal from the second input.
