ABSTRACT
Functional photonic crystals fabricated in iron garnet films are shown to provide magnetically-controllable optical switching. Transverse-electric and transverse-magnetic stop band separation in conjunction with optical gyrotropy are utilized to selectively block and transmit near-infrared light in waveguide geometries. Geometrical birefringence allows the simultaneous low- and high-birefringence in different modes necessary to create band gap separation and effective magneto-optic gyrotropy in a single device.

    We theoretically propose a method to enhance dramatically a magnetochiral (MC) effect by using the photonic crystals composed of a multiferroic material. The MC effect, the directional birefringence even for unpolarized light, is so small that it has been difficult to observe experimentally. Two...
