  • Method for preparing one dimensional spin photonic crystal device and one dimensional spin photonic crystal device prepared by the same
    Patent number: 8070919
    Abstract: Provided is a method for preparing a one-dimensional spin photonic crystal device and a one-dimensional spin photonic crystal device prepared by the same. The method comprises forming magnetic and nonmagnetic regions by the interference of laser beams generated from a femtosecond laser light source. The method of the present invention enables production of one-dimensional spin photonic crystals having excellent properties by a rapid and simple process, and is therefore suitable for high integration and large-scale production of desired devices. Further, the prepared photonic crystals exhibit excellent magneto-optical effects and are therefore applicable to development of novel optical devices, and the like.
