Strange kinetics of photons #
There has been a lot of interest in recent years in disordered photonic media in which the spatial arrangement
of scattering elements goes beyond a simple Gaussian distribution. Examples include photonic quasi-crystals,
hyper-uniform structures, and structures in which the distribution is inhomogeneous [1]. We will discuss recent
developments in the field and in particular go into the case of self-similar random systems and Lévy flights.
We will discuss optical super-diffusion and show how dynamic optical measurements can be used to determine the
fractal dimension of an optical random walk [2].
