テーマ１：Optical Tamm states in magnetophotonic crystals and their application
概要
Spectrally narrow localized surface state, the so-called optical Tamm state (OTS), was found to exist at the interface between a 1D magnetophotonic (PC1) and nonmagnetic photonic crystals (PC2). This state is associated with a sharp transmission peak and is responsible for an enhancement of Faraday rotation for corresponding wavelengths (see Fig. 1). Structures exhibiting OTSs can be useful for localizing light within any active material used as the constitutive layers of PCs or introduced at the interface between two PCs. OTSs in PCs can be used for magneto-tunable filters and various types of sensors (gas, temperature, strain).

テーマ２：2D and 3D magnetophotonic crystals
概要
2D and 3D magnetophotonic crystals (Fig. 2) are of significant interest from the application and fundamental view points. They exhibit enhancement of the magneto-optical (MO) response of magnetic constituents for wider spectral ranges due to existence of several crystallographic planes in their lattices. Directional light flow, switching and large deflection of light beams are predicted for 2D (3D) MPCs operated by external magnetic fields. It has been recently found that 2D MPCs can exhibit reversal Faraday rotation - they can inverse natural MO activity of magneto-optical materials.

テーマ３：Magnetic material/noble metal photonic nanostructures
概要
Novel magneto-optical materials (see Fig. 3) in which, for example, Bi: YIG is incorporated into or is adjoined to 1D and 2D noble metal structures supporting plasmonic resonances are of great interest for nanophotonics. They act as active elements since light beams couple to plasmonic substructure and can be controlled if subjected to the external magnetic field. For these magneto-optically active structures, enhancement of the magneto-optical response and the anomalous transmission regime can be reached because light is trapped and guided in a particular way .
