Quantum beats in the polarization of the spin-dependent photon echo from donor-bound excitons in CdTe/(Cd,Mg)Te quantum wells
S. V. Poltavtsev, I. A. Yugova, Ya. A. Babenko +6
We study the quantum beats in the polarization of the photon echo from donor-bound exciton ensembles in semiconductor quantum wells. To induce these quantum beats, a sequence compo…
Damping of Rabi oscillations in intensity-dependent photon echoes from exciton complexes in a CdTe/(Cd,Mg)Te single quantum well
S. V. Poltavtsev, M. Reichelt, I. A. Akimov +6
We study Rabi oscillations detected in the coherent optical response from various exciton complexes in a 20~nm-thick CdTe/(Cd,Mg)Te quantum well using time-resolved photon echoes.…
Photon echoes from (In,Ga)As quantum dots embedded in a Tamm-plasmon microcavity
M. Salewski, S. V. Poltavtsev, Yu. V. Kapitonov +9
We report on the coherent optical response from an ensemble of (In,Ga)As quantum dots (QDs) embedded in a planar Tamm-plasmon microcavity with a quality factor of approx. 100. Sign…
Photon echoes retrieved from semiconductor spins: access to basis for long-term optical memories
L. Langer, S. V. Poltavtsev, I. A. Yugova +6
The possibility to store optical information is important for classical and quantum communication. Atoms or ions as well as color centers in crystals offer suitable two-level syste…
Spin-flip Raman scattering of the neutral and charged excitons confined in a CdTe/(Cd,Mg)Te quantum well
J. Debus, D. Dunker, V. F. Sapega +5
Spin-flip Raman scattering of electrons and heavy-holes is studied for resonant excitation of neutral and charged excitons in a CdTe/CdMgTe quantum well. The spin…
Magnetic field control of photon echo in the electron-trion system: Shuffling of coherences between optically accessible and inaccessible states
L. Langer, S. V. Poltavtsev, I. A. Yugova +6
We report on magnetic field induced oscillations of the photon echo signal from negatively charged excitons in a CdTe/(Cd,Mg)Te semiconductor quantum well. The oscillatory signal i…
