Radiation Trapping in a Three-Dimensional Disordered Atomic Ensemble inside a Waveguide

Abstract A consistent quantum microscopic approach is used to analyze the effect of radiation trapping in a disordered ensemble of point impurity atoms in a waveguide. It is shown that in a single-mode waveguide, the period of radiation trapping grows exponentially upon an increase in the size of the medium, testifying to the Anderson localization of light.
