描述了一种新的机制，在精心制备的无序介电超晶格与一个到处真实的正介电常数强安德森局域化的光子。在三维空间中，两个光子迁移率边缘将高频和低频扩展态与由剩余几何布拉格共振产生的局部化态的中频赝隙分开。实验观察到的后果进行了讨论。
A new mechanism for strong Anderson localization of photons in carefully prepared disordered dielectric superlattices with an everywhere real positive dielectric constant is described. In three dimensions, two photon mobility edges separate high-and low-frequency extended states from an intermediate-frequency pseudogap of localized states arising from remnant geometric Bragg resonances. Experimentally observable consequences are discussed.
