Pattern Formation in the Exciton Inner Ring
M. Remeika, A. T. Hammack, S. Poltavtsev +6
We report on the spatially separated pump-probe study of indirect excitons in the inner ring in the exciton emission pattern. A pump laser beam generates the inner ring and a weake…
Drift-diffusion model of the fragmentation of the external ring structure in the photoluminescence pattern of indirect excitons in coupled quantum wells
J. Wilkes, E. A. Muljarov, A. L. Ivanov
Under optical excitation, coupled quantum wells are known to reveal fascinating features in the photoluminescence pattern originating from dipole orientated indirect excitons. The…
Kinetics of the inner ring in the exciton emission pattern in GaAs coupled quantum wells
A. T. Hammack, L. V. Butov, J. Wilkes +4
We report on the kinetics of the inner ring in the exciton emission pattern. The formation time of the inner ring following the onset of the laser excitation is found to be about 3…
First-order spatial coherence of excitons in planar nanostructures: a k-filtering effect
L. Mouchliadis, A. L. Ivanov
We propose and analyze a k-filtering effect which gives rise to the drastic difference between the actual spatial coherence length of quasi-two-dimensional (quasi-2D) excitons or m…
Strong and weak coupling limits in optics of quantum well excitons
C. Creatore, A. L. Ivanov
A transition between the strong (coherent) and weak (incoherent) coupling limits of resonant interaction between quantum well (QW) excitons and bulk photons is analyzed and quantif…
Kinetics of indirect excitons in the optically-induced exciton trap
A. T. Hammack, L. V. Butov, L. Mouchliadis +2
We report on the kinetics of a low-temperature gas of indirect excitons in the optically-induced exciton trap. The excitons in the region of laser excitation are found to rapidly -…
