Digital-Alloy Bragg Mirrors in High-Q Microcavities for Polariton Lasing
V. A. Stolyarov, A. S. Kurdyubov, A. V. Trifonov +7
We present an approach to the molecular-beam epitaxy of high-Q planar GaAs-based microcavities in which the AlGaAs high-index layers of the distributed Bragg reflectors (DBRs) are…
Exciton dynamics in CdTe/CdZnTe quantum well
A. V. Mikhailov, A. S. Kurdyubov, E. S. Khramtsov +6
Exciton energy structure and population dynamics in a wide CdTe/CdZnTe quantum well are studied by spectrally-resolved pump-probe spectroscopy. Multiple excitonic resonances in ref…
Magnetic field study of exciton nonradiative broadening excitation spectra in GaAs/AlGaAs quantum wells
M. A. Chukeev, A. S. Kurdyubov, I. I. Ryzhov +4
Exciton excited states in the quantum well are studied via their effect on the nonradiative broadening of the ground exciton resonance. Dependence of the nonradiative broadening of…
Nonlinear behaviour of the nonradiative exciton reservoir in quantum wells
A. S. Kurdyubov, A. V. Trifonov, A. V. Mikhailov +4
Excitons and free charge carriers with large wave vectors form a nonradiative reservoir, which can strongly affect properties of bright excitons due to the exciton-exciton and exci…
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…
Exciton energy oscillations induced by quantum beats
A. V. Trifonov, A. S. Kurdyubov, I. Ya. Gerlovin +5
In this paper, we experimentally demonstrate an oscillating energy shift of quantum-confined exciton levels in a semiconductor quantum well after excitation into a superposition of…
Impurity-induced modulation of terahertz waves in optically excited GaAs
A. S. Kurdyubov, A. V. Trifonov, I. Ya. Gerlovin +2
The effect of the photoinduced absorption of terahertz (THz) radiation in a semi-insulating GaAs crystal is studied by the pulsed THz transmission spectroscopy. We found that a bro…
Nuclear spin cooling by helicity-alternated optical pumping at weak magnetic fields in -GaAs
P. S. Sokolov, M. Yu. Petrov, K. V. Kavokin +8
The spin dynamics of localized donor-bound electrons interacting with the nuclear spin ensemble in -doped GaAs epilayers is studied using nuclear spin polarization by light with…
Excitons in asymmetric quantum wells
P. S. Grigoryev, A. S. Kurdyubov, M. S. Kuznetsova +6
Resonance dielectric response of excitons is studied for the high-quality GaAs/InGaAs heterostructures with wide asymmetric quantum wells (QWs). To highlight effects of the QW asym…
Nontrivial relaxation dynamics of excitons in high-quality InGaAs/GaAs quantum wells
A. V. Trifonov, S. N. Korotan, A. S. Kurdyubov +8
Photoluminescence (PL) and reflectivity spectra of a high-quality InGaAs/GaAs quantum well structure reveal a series of ultra-narrow peaks attributed to the quantum confined excito…
