METHOD AND DEVICE FOR STABILIZING THE STATE OF POLARIZATION OF A POLARIZATION MULTIPLEXED OPTICAL RADIATION
摘要
A device (100) and method for stabilizing the polarization of a polarization multiplexed optical radiation comprising an identified channel which is provided with a pilot signal. The device (100) and method are based on providing to the polarization multiplexed optical radiation a controllable polarization transformation; measuring the optical power of a polarized portion of the identified channel downstream the polarization transformation; controlling, responsively to said optical power, the controllable polarization transformation so that the identified channel downstream the polarization transformation has a predefined polarization azimuth; providing to the optical radiation downstream the polarization transformation a further controllable polarization transformation; measuring the optical power of a polarized portion of the identified channel downstream the further controllable polarization transformation; controlling, responsively to said optical power, the further controllable polarization transformation so that the identified channel downstream the further controllable polarization transformation has a predefined state of polarization (SOP our).
