Abstract

This is a theory for the effect of localization on the super-Poissonian noise of radiation propagating through an absorbing disordered waveguide. Localization suppresses both the mean photon current Ī and the noise power P, but the Fano factor P/Ī is found to remain unaffected. For strong absorption the Fano factor has the universal value 1+32f (with f the Bose-Einstein function), regardless of whether the waveguide is long or short compared to the localization length.
