Phys. Rev. Lett. 58, 2486–2489 (1987)Strong localization of photons in certain disordered dielectric superlatticesReceived 5 March 1987; published in the issue dated 8 June 1987 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. © 1987 The American Physical Society URL:
