Photonic band structure
The question of equivalence between photon propagation in disordered dielectric media and electron propagation in disordered conducting media has been intensively investigated within the last several years. Recently, the question of equivalence has been addressed with respect to ordered, or spatially periodic, media by Yablonovitch4 and by John5, yielding interesting new perspectives on the band theory of spin-one particles and "strong," or Anderson, localization, with potentially important implications for the development of optoelectronic devices.
