In this paper we present a number of measurements of the magneto-optic (MO) polarization rotation effect in MO glasses. We then show three design concepts of MO based devices that are of interest for optical communications applications. The first device is a tunable optical polarization controller, the second is a polarization filter that passes through only a specific point on the Poincaré sphere and the third is a MO Fabry-Perot resonator that enhances the MO effect and can be used inside an all-optical switch or as part of a polarization coding module.
