A hybrid mo-demodulation approach, fully insensitive to the phase noise induced by the sources, is described for CDMA applications at optical frequencies. It is analytically demonstrated that, using bipolar codes in conjunction with polarisation modulation, the considered system can improve the performance of coherent schemes with not negligible laser linewidths, as well as the performance of more conventional noncoherent schemes based on intensity modulation and unipolar codes.
