ABSTRACT:
The present invention relates to an optical device comprising a wave-guide and a polarization converter, the wave-guide and the polarization converter comprising one common unit, the length of the wave-guide being so chosen in relation to the rotation of the polarization-state of an input signal that the device is independent of the polarization as well as a method for polarization-independent processing of an optical signal. The polarization of the signal is rotated when it goes through a wave-guide, the rotation taking place in the wave-guide itself and the length of the wave-guide being so chosen that the processing of the signal is independent of the polarization-state upon incidence.
