Photonic heterostructures with Levy-type disorder: statistics of
coherent transmission
   [PDF]

A. A. Fernandez-Marin, J. A. Mendez-Bermudez, Victor A. Gopar
We study the electromagnetic transmission $T$ through one-dimensional (1D) photonic heterostructures whose random layer thicknesses follow a long-tailed distribution --L\'evy-type distribution. Based on recent predictions made for 1D coherent transport with L\'evy-type disorder, we show numerically that for a system of length $L$ (i) the average $<-\ln T> \propto L^\alpha$ for $0<\alpha<1$, while $<-\ln T> \propto L$ for $1\le\alpha<2$, $\alpha$ being the exponent of the power-law decay of the layer-thickness probability distribution; and (ii) the transmission distribution $P(T)$ is independent of the angle of incidence and frequency of the electromagnetic wave, but it is fully determined by the values of $\alpha$ and $<\ln T>$.
