Position-Dependent Diffusion of Light in Disordered Waveguides
Position-Dependent Diffusion of Light in Disordered Waveguides
Diffusion has been widely used to describe a random walk of particles or waves, and it requires only one parameter -- the diffusion constant. For waves, however, diffusion is an approximation that disregards the possibility of interference. Anderson localization, which manifests itself through a vanishing diffusion coefficient in an infinite …
