1. A system comprising:

  • a transmitting device to modulate orthogonally polarized optical carriers with independent information bearing waveforms; and

    a receiving device including (i) a cross polarization interference canceler that comprises a plurality of optical elements each supporting a transfer function to collectively mitigate cross polarization interference and to reconstruct the information bearing waveforms recovered from the orthogonally polarized optical carriers and (ii) a plurality of receivers each to receive an optical signal from the cross polarization interference canceler.
