Effects of localization and amplification on distribution of intensity transmitted through random media
Alexey Yamilov, Hui Cao
Abstract
We numerically study the statistical distribution of intensity transmitted through quasi-one dimensional random media by varying the dimensionless conductance g and the amount of absorption or gain. Markedly non-Rayleigh distribution is found to be well fitted by the analytical formula of Nieuwenhuizen et al, Phys. Rev. Lett. 74, 2674 (1995) with a single parameter g. We show that in the passive random system g is uniquely related to g, while in amplifying/absorbing random media g also depends on gain/absorption coefficient.
