Phase randomization in disordered layered systems

TL;DR

This paper investigates how light propagates through disordered layered systems, revealing that the phase distribution of transmission coefficients becomes stationary with increasing layers, enabling the definition of a phase randomization length scale.

Contribution

It introduces the concept of phase randomization length scale in disordered layered media by analyzing the convergence of phase distribution functions.

Findings

Phase distribution tends to a stationary non-uniform distribution with more layers.

Exponential convergence allows defining a phase randomization length scale.

The study provides a quantitative framework for phase behavior in disordered systems.

Abstract

The propagation of light through a disordered layered system is studied. It is shown that distribution function of the transmission coefficient phase tends to stationary non-uniform distribution as the number of layers increases. The exponential convergence to the stationary distribution allows unambiguous definition of the phase randomization length scale.
