1. An optical data signal transmitter comprising:

  • at least one optical carrier generator, each generating an optical carrier signal having two side frequencies derived from a source frequency;

    at least one data modulator for modulating data onto the at least one optical carrier signal, creating at least one optical data signal including modulated data and having a first polarization state; and

    at least one polarization transformer for encoding a portion of the modulated data and a first of the two side frequencies of the at least one optical data signal with a second polarization state, the second polarization state being orthogonal to the first polarization state.
