Abstract:
A simple approach to the problem of light localization in one-dimensional system is presented. The role of the Bragg reflection in one-dimensional localization of light is discussed. Contrary to the existent viewpoint, we show that the origin of band gaps of regular crystals and the localization due to disorder have a common nature, that is, the Bragg reflection. We expand the concept of band structure to random systems of finite thickness L and relate the Anderson localization of light with the total band gap growth, which is observed in our computer simulation of disordered system, as L increases.
