ABSTRACT:
A magneto-optic modulator and method are provided. An optical waveguide having a magneto-optic active medium is magnetized by a biasing magnetic field. The magnetization of the magneto-optic active medium is modulated thereby causing a variation in the Faraday effect on optical signals passing through the magneto-optic medium. The result is a polarization modulated optical signal.
