Abstract:
1. A system ( 1 ) for stabilizing the polarization of an input light beam ( 2 ′), including means ( 3 ) for optically guiding the input light beam ( 2 ′), characterized in that said optical guide means ( 3 ) exhibit a Kerr type non-linearity and a low polarization-mode dispersion having a value ranging between 0.001 and 0.07 picoseconds per root kilometer, and in that the system ( 1 ) also comprises means ( 4 ) for generating a pump light beam ( 4 ′) the polarization of which is fixed over time and the spectrum of which is adapted to minimize the Brillouin scattering within said optical guide means ( 3 ), said generation means ( 4 ) being arranged such that the input ( 2 ′) and pump ( 4 ′) light beams are contra-propagating beams within the optical guide means ( 3 ).
