Title:
SYSTEM FOR MONITORING ALL-OPTICAL POLARIZATION HAVING A CONTRA-PROPAGATING PUMP BEAM
Document Type and Number:
WIPO Patent Application WO/2011/033203
Kind Code:
A8
Abstract:
The present invention relates to a system (1) for stabilizing the polarization of an input light beam (2'), including a means (3) for optically guiding the input light beam (2'). In said system, the optical guide means (3) has Kerr nonlinearity and low polarization mode dispersion. Additionally, said system (1) also includes a means (4) for generating a pump light beam (4'), the polarization of which is fixed over time and the spectrum of which is suited for the Brillouin scattering threshold in the optical guide means (3). Said generating means (4) is arranged such that the input light beam (2') and pump light beam (4') are contra-propagating in the optical guiding means (3).
