Routing the emission of a near-surface light source by a magnetic field
F. Spitzer, A. N. Poddubny, I. A. Akimov +10
Magneto-optical phenomena such as the Faraday and Kerr effects play a decisive role for establishing control over polarization and intensity of optical fields propagating through a…
Long-range p-d exchange interaction in a ferromagnet-semiconductor Co/CdMgTe/CdTe quantum well hybrid structure
I. A. Akimov, M. Salewski, I. V. Kalitukha +14
The exchange interaction between magnetic ions and charge carriers in semiconductors is considered as prime tool for spin control. Here, we solve a long-standing problem by uniquel…
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.…
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…
Excitation of magnon accumulation by laser clocking as a source of long-range spin waves in transparent magnetic films
M. Jäckl, V. I. Belotelov, I. A. Akimov +4
Optical tools are of great promise for generation of spin waves due to the possibility to manipulate on ultrashort time scales and to provide local excitation. However, a single la…
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…
