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…
Accurate photon echo timing by optical freezing of exciton dephasing and rephasing in quantum dots
A. N. Kosarev, H. Rose, S. V. Poltavtsev +7
Semiconductor quantum dots are excellent candidates for ultrafast coherent manipulation of qubits by laser pulses on picosecond timescales or even faster. In inhomogeneous ensemble…
The in-plane anisotropy of the hole factor in CdTe/(Cd,Mg)Te quantum wells studied by spin-dependent photon echoes
S. V. Poltavtsev, I. A. Yugova, A. N. Kosarev +6
We use the two-pulse spin-dependent photon echo technique to study the in-plane hole spin anisotropy in a 20~nm-thick CdTe/CdMgTe single quantum well by exciting…
Microscopic dynamics of electron hopping in a semiconductor quantum well probed by spin-dependent photon echoes
A. N. Kosarev, S. V. Poltavtsev, L. E. Golub +10
Spin-dependent photon echoes in combination with pump-probe Kerr rotation are used to study the microscopic electron spin transport in a CdTe/(Cd,Mg)Te quantum well in the hopping…
