详细
The dynamically compressed coherent exciton-polariton condensate state was implemented at the low polariton (LP) band bottom in GaAs microcavity resonantly excited in a wide range of wavevectors by the convergent 2.5-ps long Gaussian linearly polarized beam when the active region of the cavity was ahead of the waist. Formation of the dynamically compressed condensate state at the LP band bottom and its further dynamics are shown to be well described by the Gross-Pitaevskii equation. The state persists for several picosecond until LP-LP repulsion causes its expansion in both spatial and momentum spaces. Dynamic compression of an elliptically polarized LP system is found to occur without preserving its initial polarization: the dynamic compression of weakly interacting components with σ+ and σ− polarization occurs almost independently.
