Wiersma et al. have reported near-infrared optical transmission and coherent backscattering data from strongly scattering slabs of micrometre-sized semiconductor particles. Their optical transmission was much weaker, and the angular shape of their coherent backscattering more rounded, than would be expected for classical diffusive light propagation without absorption. The authors interpret this as evidence for the onset of strong localization of light, but we find that their data can be… 

Observation of the critical regime near Anderson localization of light.

TLDR
Time resolved measurements of light transport through strongly scattering samples with kl* values as low as 2.5 constitute an experimental realization of the critical regime in the approach to Anderson localization.

Observation of Anderson localization of light in three dimensions.

TLDR
Using time-resolved transmission measurements, indications of Anderson localization of light in bulk three-dimensional systems are found and it is shown that in these samples the control parameter is given by the mean free path times the wavenumber as required by the Ioffe-Regel criterion.

Probing Anderson localization of light by weak non-linear effects

Breakdown of wave transport due to strong disorder is a universal phenomenon known as Anderson localization (AL). It occurs because of the macroscopic population of reciprocal multiple scattering

Experimental signatures of Anderson localization of light in three dimensions

The observation of Anderson localization of light has long been hindered by the lack of clear-cut experimental signatures. Static transmission measurements for instance would show an exponential

Deducing effective light transport parameters in optically thin systems

We present an extensive Monte Carlo study on light transport in optically thin slabs, addressing both axial and transverse propagation. We systematically characterize diffusive transport in this

Coherent backscattering and Anderson localization of light Aegerter

In this review we discuss localization of waves by multiple scattering. In the weak case, also known as coherent backscattering, there is a twofold enhancement of the reflected intensity in the back

Crossover from renormalized to conventional diffusion near the three-dimensional Anderson localization transition for light

We report on anomalous light transport in the strong scattering regime. Using low-coherence interferometry, we measure the reflection matrix of titanium dioxide powders, revealing crucial features of

Weak localization of photon noise

We present an experimental study of coherent backscattering (CBS) of photon noise from multiple scattering media. We use a pseudothermal light source with a microsecond coherence time to produce a

Seeing Anderson localization

We propose an optical scheme to literally see Anderson localization by varying the optical wavelength or the angle of incidence in order to tune between localized and delocalized states in a random

Among the unusual transport properties predicted for disordered materials is the Anderson localization phenomenon. This is a disorder-induced phase transition in the electron-transport behaviour from
