Dispersion and damping of multi-quantum well polaritons from resonant Brillouin scattering by folded acoustic modes
arXiv:1105.2229 · doi:10.1103/PhysRevB.85.041302
Abstract
We report on confined exciton resonances of acoustic and folded acoustic phonon light scattering in a GaAs/AlAs multi-quantum-well. Significant variations of the line shifts and widths are observed across the resonance and quantitatively reproduced in terms of the polariton dispersion. This high resolution Brillouin study brings new unexpectedly detailed informations on the polariton dynamics in confined systems.
