Abstract:
A method for polarization control of an optical signal, comprising:converting a polarization of the optical signal using polarization acutuators, with arbitrary, freely and interruption free selectable individual phase angle differences as individual angle coordinates, at least partially into a respective orthogonal, which together form a polarization transformer with a total delay and a total phase angle difference as a total angle coordinate between the polarization and a respective orthogonal, in which an individual angle coordinate is varied as a function of another angle coordinate, wherein the amount (|d&zgr;1|, |d&zgr;2|, |d&zgr;|, |d&zgr;*(2*iâˆ’nâˆ’1)/(nâˆ’1)|) of the variation (d&zgr;1, d&zgr;2, d&zgr;, d&zgr;*(2*iâˆ’nâˆ’1)/(nâˆ’1)) of an individual angle coordinate is limited for sequences of desired polarization transformations.
