Transient photon echoes from donor-bound excitons in ZnO epitaxial layers
S. V. Poltavtsev, A. N. Kosarev, I. A. Akimov +8
The coherent optical response from 140~nm and 65~nm thick ZnO epitaxial layers is studied using transient four-wave-mixing spectroscopy with picosecond temporal resolution. Resonan…
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…
Single-shot measurement of transient nuclear magnetization with spin-noise spectroscopy in n-GaAs microcavities
I. I. Ryzhov, S. V. Poltavtsev, K. V. Kavokin +9
We exploit spin noise spectroscopy (SNS) to directly observe build-up of dynamic nuclear polarization and relaxation of a perturbed nuclear spin-system to its equilibrium state in…
Optics of spin-noise-induced gyrotropy of asymmetric microcavity
S. V. Poltavtsev, I. I. Ryzhov, R. V. Cherbunin +5
The optical gyrotropy noise of a high-finesse semiconductor Bragg microcavity with an embedded quantum well (QW) is studied at different detunings of the photon mode and the QW exc…
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…
Effect of annealing on the hyperfine interaction in InAs/GaAs quantum dots
M. Yu. Petrov, I. V. Ignatiev, S. V. Poltavtsev +4
The hyperfine interaction of an electron with nuclei in the annealed self-assembled InAs/GaAs quantum dots is theoretically analyzed. For this purpose, the annealing process, and e…
