1. A method for controlling the polarization of an optical signal comprising:

  • passing a first non-linearly-polarized optical signal having a first polarization ellipticity through a polarization varying device to produce a second non-linearly-polarized optical signal having a second polarization ellipticity greater than the first polarization ellipticity;

    characterizing the second polarization ellipticity of the second non-linearly-polarized optical signal; and

    controlling the orientation of the polarization varying device to maintain a predetermined characterization of the polarization ellipticity of the second polarization ellipticity of the second non-linearly-polarized optical signal.
