  • Micron-size optical faraday rotator
    Patent number: 7965436
    Abstract: In an embodiment, micron-size optical Faraday rotator includes a non-magnetic dielectric waveguide. The waveguide includes a plurality of perforations to form a photonic crystal. A magnetic cladding is disposed on at least one side of the waveguide. The Faraday rotator causes non-reciprocal Faraday rotation of an optical signal propagating within the waveguide.
