title: Anomalous flow of light near a photonic crystal pseudo-gap.
abstract: Two different transport regimes of light are observed in reflection from the same disordered photonic crystal. A model based on the scaling theory of localization explains the behavior of the path length-resolved reflection at two different probing wavelengths. Our results demonstrate the continuous renormalization of the photon diffusion coefficient measured in reflection from random media.
