Dynamic light diffusion, Anderson localization and lasing in disordered inverted opals: 3D ab-initio Maxwell-Bloch computation

  title={Dynamic light diffusion, Anderson localization and lasing in disordered inverted opals: 3D ab-initio Maxwell-Bloch computation},
  author={Claudio Conti and Andrea Fratalocchi},
We report on 3D time-domain parallel simulations of Anderson localization of light in inverted disordered opals displaying a complete photonic band-gap. We investigate dynamic diffusion processes induced by femtosecond laser excitations, calculate the diffusion constant and the decay-time distribution versus the strength of the disorder. We report evidence of the transition from delocalized Bloch oscillations to strongly localized resonances in self-starting laser processes. 

Transition from light diffusion to localization in three-dimensional amorphous dielectric networks near the band edge

It is shown that the transition to localization at the mobility edge can be described using the self-consistent theory of localization based on the concept of a position-dependent diffusion coefficient, and that transport sets off diffusive but, with increasing slab thickness, crosses over gradually to a faster decay, signaling localization.

We consider a one-dimensional photonic crystal embedded in a two-level medium with various degrees of disorder, such that the tail of localized states in the forbidden gap is resonant with

Inhibited spontaneous emission using gaplike resonance in disordered photonic structures

We study the mesoscopic light transport and emission dynamics in a photonic structure made up of monodisperse scatterers as it undergoes an order-disorder structural transition. We have found a

A Self-Consistent Quantum Field Theory for Random Lasing

The spatial formation of coherent random laser modes in strongly scattering disordered random media is a central feature in the understanding of the physics of random lasers. We derive a quantum

A quantum chaos study on the localization of light in a resonator-based photonic crystal

We explore the issue of eigenstate localization in a two-dimensional photonic resonator lattice. In the system of our purpose, by harmonically modulating coupling constants between the resonators an

Anderson localization at the hybridization gap in a plasmonic system

Disorder-induced Anderson localization in quasiparticle transport is a challenging problem to address, even more so in the presence of dissipation as the symptoms of disorder-induced localization are

A Path Integral Monte Carlo Study of Anderson Localization in Cold Gases in the Presence of Disorder

We revisit the problem of Anderson localization in a trapped Bose–Einstein condensate in 1D and 3D in a disordered potential, applying Quantum Monte Carlo technique because the disorder cannot be

Excitation-dependent diffuse super-reflection from a random laser

Enhancement of the diffusive albedo from a random amplifying medium is discussed. A pump-probe setup is used to study the amplification of the reflected probe pulse light outside the backscattering

We investigate light propagation in a two-dimensional aperiodic refractive index lattice realized using the interference of multiple Mathieu–Gauss beams. We demonstrate experimentally and numerically

This paper is a study of a statistical mechanics model for the interactions of light modes confined in an optically active random media. The results of numerical simulations show that the onset of
