Dynamic light diffusion, Anderson localization and lasing in disordered inverted opals: 3D ab-initio Maxwell-Bloch computation
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.Comment: 4 pages, 5 figure
