Dynamics and control of nonradiative excitons - free carriers mixture in GaAs/AlGaAs quantum wells
A. S. Kurdyubov, A. V. Trifonov, B. F. Gribakin +9
Dynamics of nonradiative excitons with large in-plane wave vectors forming a so-called reservoir is experimentally studied in a high-quality semiconductor structure containing a 14…
Long-living dark coherence brought to light by magnetic-field controlled photon echo
I. A. Solovev, I. I. Yanibekov, Yu. P. Efimov +5
Larmor precession of the quasiparticle spin about a transverse magnetic field leads to the oscillations in the spontaneous photon echo signal due to the shuffling of the optical co…
Modelling and optimization of the excitonic diffraction grating
P. Yu. Shapochkin, Yu. V. Petrov, S. A. Eliseev +3
Periodical spatial modulation of the excitonic resonance in a quantum well could lead to the formation of a new highly directional and resonant coherent optical response -- resonan…
Nanosecond-scale magneto-exciton energy oscillations in quantum wells
A. V. Trifonov, E. S. Khramtsov, K. V. Kavokin +6
We report on the experimental evidence for a nanosecond time-scale spin memory based on nonradiative excitons. The effect manifests itself in magnetic-field-induced oscillations of…
