Probing Anderson localization of light via decay rate statistics

Abstract

We have studied the distribution of resonant widths $P(\Gamma )$ in one-, two- and three dimensional multiple light scattering systems. $P(\Gamma )$ should follow a universal power law $P(\Gamma )\sim {\Gamma }^{-1}$ in the localized regime as confirmed by extensive numerical calculations. This behavior can be interpreted as an unambiguous signature of exponential Anderson localization of light in open systems.
