Abstract
Methods and apparatus for adaptively compensating optical signal distortion, including polarization mode dispersion, chromatic dispersion, and the like, using magneto-optic devices are provided. One optical distortion compensator according to this invention includes at least one polarization transformer that includes a magneto-optic rotator in combination with a variable delay device. The magneto-optic rotator, after transforming the state of polarization of an incident optical signal, delivers the transformed signal to the variable delay device.
