Analysis of Opal Template for Three Dimentional Magnetophotonic Crystals

Periodic structures of dielectric materials in submicrometer are currently paid much attention as photonic crystals (PC) with photonic band gap (PBG), which prohibits light of specific wavelength from propagating in certain directions. We reported one-dimensional magnetophotonic crystals (1D-MPCs) constructed of dielectric multi layers and a magnetic defect layer obtained large enhancement of Faraday rotation in localized mode. On the other hand, three-dimensional photonic crystals (3D-PCs) have more capability as the materials exhibit remarkable effects such as acute angle optical waveguides, super prism, and magnetophotonic crystals (MPCs). In order to control that unique effect by applying external magnetic field, fabrication of three-dimensional magnetophotonic crystals (3D-MPCs) with magnetic materials is required.
