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…
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…
Inversion of Zeeman splitting of exciton states in InGaAs quantum wells
P. S. Grigoryev, O. A. Yugov, S. A. Eliseev +5
Zeeman splitting of quantum-confined states of excitons in InGaAs quantum wells (QWs) is experimentally found to depend strongly on quantization energy. Moreover, it changes sign w…
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…
Spin-noise-based magnetometry of an -doped GaAs microcavity in the field of elliptically polarized light
I. I. Ryzhov, G. G. Kozlov, D. S. Smirnov +8
Recently reported optical nuclear orientation in the -doped GaAs microcavity under pumping in nominal transparency region of the crystal [Appl. Phys. Lett. , 24240…
Excitons in square quantum wells: microscopic modeling and experiment
E. S. Khramtsov, P. A. Belov, P. S. Grigoryev +7
The binding energy and the corresponding wave function of excitons in GaAs-based finite square quantum wells (QWs) are calculated by the direct numerical solution of the three-dime…
Decrease of heavy-hole exciton mass induced by uniaxial stress in GaAs/AlGaAs quantum well
D. K. Loginov, P. S. Grigoryev, E. V. Ubiyvovk +5
It is experimentally shown that the pressure applied along the twofold symmetry axis of a heterostructure with a wide GaAs/AlGaAs quantum well leads to considerable modification of…
