Effect of the incoherent scattering of polaritons on the dynamics of stimulated polariton-polariton scattering in GaAs microcavities

Abstract:
It has been found that interband illumination strongly affects the dynamics of parametric polariton scattering in planar GaAs microcavities under resonant photoexcitation above the inflection point of the polariton dispersion curve: illumination with a power density of about 0.1% of the resonance value reduces the threshold density for the appearance of stimulated scattering by more than 15%. It has been shown that the effect is attributed to a change in the resonance energy of the pumped mode due to an increase in the density of long-lived exciton-like polaritons formed owing to the scattering of resonantly-excited polaritons on photoexcited free carriers.
