Abstract: In some implementations, an optical receiver includes a polarization beam splitter configured to split a reception signal into a first polarization reception signal and a second polarization reception signal, a first demultiplexing component configured to demultiplex the first polarization reception signal into a first optical signal and a second optical signal associated with a first polarization, a second demultiplexing component configured to demultiplex the second polarization reception signal into a third optical signal and a fourth optical signal associated with a second polarization, a first demodulation component configured to mix the first optical signal and the third optical signal with a first local oscillator signal to demodulate the first optical signal and the third optical signal, and a second demodulation component configured to mix the second optical signal and the fourth optical signal with a second local oscillator signal to demodulate the second optical signal and the fourth optical signal
