Magnetophotonic Crystals: Now and Future
When the constitutive elements of photonic crystals (PCs) are magnetic, or even only a defect introduced in PCs is magnetic, the resultant PCs exhibit very unique optical and magneto-optical properties. The strong photon confinement in the bulk of magnetic PCs results in large enhancement in linear and nonlinear magneto-optical responses of the media. Novel functions, such as the band Faraday effect, magnetic super-prism effect and non-reciprocal or magnetically controllable photonic band structure, are predicted to occur theoretically. All the unique features of the media arise from the existence of its magnetization, and hence they are called magnetophotonic crystals providing the spin-dependent nature in PCs.
