TOM 11 Waves in Complex Photonic Media

Light waves in complex environments

Diederik Wiersma

INRIM, LENS, Univ. of Florence, Italy

We will give an overview of recent results in the field of light waves in complex environments. Then we will focus on random lasers and their use for super resolution spectroscopy.

Disorder and topology in planar arrays of resonant scatterers

Sergey E. Skipetrov, Pierre Wulles

Universite Grenoble Alpes, CNRS, LPMMC, 38000 Grenoble, France

We study the impact of disorder- and topology-induced effects on light scattering in planar arrays of resonant scatterers (“atoms”). On the one hand, we show how the topological phenomena influence the strength of Anderson localization due to disorder. On the other hand, we explore the possibility of inducing nontrivial topological states by introducing disorder in an otherwise topologically trivial system. Our results demonstrate that studying topological properties provides an additional insight into wave physics of disordered systems.

Fluctuating forces induced by non equilibrium and coherent light flow

Erik Akkermans

Technion, Israel

We show that mesoscopic coherent fluctuations of light propagating in random media induce fluctuating radiation forces. A hydrodynamic Langevin approach is used to describe the coherent light fluctuations, whose noise term accounts for mesoscopic coherent effects. This description -- generalizable to other quantum or classical wave problems -- allows to understand coherent fluctuations as a non equilibrium light flow. The strength of these fluctuating forces is determined by a single dimensionless and tunable parameter, the conductance. Orders of magnitude of these fluctuation forces are offered which show experimental feasibility.
