Effects of localization and amplification on distribution of intensity transmitted through random media
arXiv:cond-mat/0405498 · doi:10.1103/PhysRevE.70.037603
Abstract
We numerically study the statistical distribution of intensity transmitted through quasi-one dimensional random media by varying the dimensionless conductance and the amount of absorption or gain. Markedly non-Rayleigh distribution is found to be well fitted by the analytical formula of Nieuwenhuizen {\it et al}, Phys. Rev. Lett. {\bf 74}, 2674 (1995) with a single parameter . We show that in the passive random system is uniquely related to , while in amplifying/absorbing random media also depends on gain/absorption coefficient.
