Fabrication of multi-dimensional magnetophotonic crystals controlled structure at unit of nano-meter and their linear and non-linear optical function

当光子晶体的组成材料是磁性的，甚至只有一个缺陷是磁性的时，所得到的光子晶体具有非常独特的光学和磁光特性：磁性缺陷附近的强光子约束导致介质的线性和非线性磁光响应大大增强。理论上预言了新的功能，如带法拉第效应，磁超棱镜效应和非互易或磁可控光子带结构。磁光子晶体（Magnetophotonic Crystals，MPC）是一种具有自旋相关性质的介质。在一维情况下，我们得到了几乎完全的石榴石结构或石榴石结构的层状介质，并对其性质进行了详细的理论和实验研究。由于其形成的便利. ...更多信息 这些介质已经在光隔离器器件、空间光调制器和传感器/成像器系统中发现了它们的潜在应用。最近的兴趣在这一领域的组合现象，如PBG，局域模式和表面等离子体激元的激发之间的关系，或在远红外观察到的磁折射效应的增强。另一个重要的问题是形成具有完美的2D或3D空间对称性的MPC。已经进行了几次试验，但结果仍不令人满意。由于这些样品具有独特的自旋相关的线性和非线性光学性质，尽管其结构有时非常复杂，但仍需要进一步的研究来创造新的介质，特别是作为自旋波传播介质的MPC。通过利用光子带隙或局域化，自旋波的独特操纵将是可行的。这对于从GHz到THz的高频应用是有吸引力的。少

When the constitutive materials of photonic crystals(PCs) are magnetic, or even only a defect in PCs is magnetic, the resultant PCs exhibit very unique optical and magneto-optical(MO) properties : The strong photon confinement in the vicinity of magnetic defects results in large enhancement in linear and nonlinear magneto-optical responses of the media. Novel functions, such as 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 magnetization in media, and hence they are called magnetophotonic crystals(MPCs) providing the spin-dependent nature in PCs.As far as one-dimensional case is concerned, almost perfect layered media with dielectric-garnet composite or all garnet structures have been obtained and their properties were studied experimentally and theoretically in detail. Because of the facility in their formatio … More n, these media have already found their potential applications in optical isolator devices, spatial light modulators and sensor/imager systems. Recent interests in this area are combined phenomena such as the relation among PBG, localized modes and the excitation of surface plasmon, or the enhancement of magnetorefractive effect observed in the far infrared. Their experimental investigations have already been started.Another important issue is the formation of MPCs with perfect 2D or 3D spatial symmetries. Several trials have been done, but the results are still unsatisfactory. Because these samples are expected to exhibit unique spin-dependent linear and nonlinear optical properties, though the structures are sometimes very complicated, further vigorous studies for creating the novel media are necessary.Particular attention should be made to MPCs as media of spin wave propagations. By utilizing the PBG or localization, unique manipulation of spin waves will be feasible. This is attractive for high frequency applications ranging from GHz to THz. Less
