A novel coherent optical system is proposed that is independent of the received state of polarization and widely insensitive to phase‐noise. It is based on transmission of the phase‐modulated signal and a reference carrier on two orthogonal polarizations and that makes feasible PSK heterodyne systems with phase‐noise affected sources with less than 3 dB penalty.
