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