Method for compensating polarization mode dispersion in a waveguide and a polarization mode dispersion compensator
First Claim
1. A method for compensating for polarization mode dispersion, the method comprising the steps of supplying an optical signal to be compensated to an arrangement having an optical waveguide with principal modes having two substantially different propagation constants, and having a plurality of electrooptical mode converters for converting the principal modes of the waveguide to one another, and individually actuating more than two of the electrooptical mode converters or more than two groups of the electrooptical mode converters by more than two control voltages which are governed by more than two parameters, wherein the polarization mode dispersion of the optical signal is compensated.
