Temporal sorting of optical multi-wave-mixing processes in semiconductor quantum dots
S. Grisard, A. V. Trifonov, H. Rose +8
Coherent control of ensembles of light emitters by means of multi-wave mixing processes is key for the realization of high capacity optical quantum memories and information process…
Extending the time of coherent optical response in ensemble of singly-charged InGaAs quantum dots
A. N. Kosarev, A. V. Trifonov, I. A. Yugova +10
The ability to extend the time scale of the coherent optical response from large ensembles of quantum emitters is highly appealing for applications in quantum information devices.…
Strong enhancement of heavy-hole Landé factor in InGaAs symmetric quantum dots revealed by coherent optical spectroscopy
A. V. Trifonov, I. A. Akimov, L. E. Golub +9
We reveal the existence of a large in-plane heavy-hole factor in symmetric self-assembled (001) (In,Ga)As/GaAs quantum dots due to warping of valence band states. This warping…
Optical orientation of hole magnetic polarons in (Cd,Mn)Te/(Cd,Mn,Mg)Te quantum wells
E. A. Zhukov, Yu. G. Kusrayev, K. V. Kavokin +8
The optically induced spin polarization in (Cd,Mn)Te/(Cd,Mn,Mg)Te diluted-magnetic-semiconductor quantum wells is investigated by means of picosecond pump-probe Kerr rotation. At 1…
Exciton-Trion Coherent Interactions in a CdTe/CdMgTe Quantum Well
G. Moody, I. A. Akimov, H. Li +7
We present a collection of zero-, one- and two-quantum two-dimensional coherent spectra of excitons and trions in a CdTe/(Cd,Mg)Te quantum well. The set of spectra provides a uniqu…
Fifth-order nonlinear optical response of excitonic states in an InAs quantum dot ensemble measured with 2D spectroscopy
G. Moody, R. Singh, H. Li +5
Exciton, trion and biexciton dephasing rates are measured within the inhomogeneous distribution of an InAs quantum dot (QD) ensemble using two-dimensional Fourier-transform spectro…
Collective single mode precession of electron spins in a quantum dot ensemble
A. Greilich, S. Spatzek, I. A. Yugova +6
We show that the spins of all electrons, each confined in a quantum dot of an (In,Ga)As/GaAs dot ensemble, can be driven into a single mode of precession about a magnetic field. Th…
Nonequilibrium nuclear-electron spin dynamics in semiconductor quantum dots
D. H. Feng, I. A. Akimov, F. Henneberger
We study the spin dynamics in charged quantum dots in the situation where the resident electron is coupled to only about 200 nuclear spins and where the electron spin splitting ind…
