Abstract

Abstract Stationary and transient spectroscopy of excitonic induction is applied for measuring the rates of the processes controlling the efficiency of the coherence transfer under the photon‐exciton transformations in GaAs/AlGaAs structures with single quantum wells.

Coherent control of excitonic excitations in II–VI quantum wells

T. Voss, Hans Georg Breunig, Ilja Rückmann +1 more

Abstract We present results of experimental work in which the coherent‐control technique has been applied to study the coherent manipulation of excitonic polarization in ZnSe quantum‐well samples. We will introduce the linear control of excitonic polarization in pulse‐transmission experiments and afterwards focus on the question if and how the optical transition from the excitonic states to the bound‐biexciton state can be subject to a directed coherent control. The experimental results will be compared to simulations based on a microscopic theory and will also be explained on the base of a phenomenological few‐level model. The overall suitability of coherent control for the investigation of exciton systems in low‐dimensional wide‐gap materials will be discussed. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Investigation of the mechanisms of exciton coherence relaxation in single GaAs/AlGaAs quantum wells by the methods of excitonic induction

S. V. Poltavtsev, V. V. Ovsyankin, Boris V. Stroganov +4 more

The mechanisms of exciton coherence relaxation in GaAs quantum wells in the linear mode have been experimentally investigated. An experimental technique has been developed for measuring the total phase relaxation rate, rates of reversible and temperature-irreversible excitonic phase relaxation, and the radiative decay rate Γ R of excitonic polarization. The experimental values of Γ R for a quantum well of specified thickness, obtained for a series of samples, have a spread not larger than 15%. This accuracy made it possible to estimate the shape of the dependence of Γ R on the well thickness L Z . It is experimentally found that Γ R is temperature-independent up to 80 K.

Two‐colour photocurrent detection technique for coherent control of a single InGaAs/GaAs quantum dot

Stephen J. Boyle, A. J. Ramsay, Roman S. Kolodka +5 more

Abstract We present a two‐colour photocurrent detection method for coherent control of a single InGaAs/GaAs self‐assembled quantum dot. A pulse shaping technique provides a high degree of control over picosecond optical pulses. Rabi rotations on the exciton to biexciton transition are presented, and fine structure beating is detected via time‐resolved measurements. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Coherent control as a probe of scattering mechanisms in semiconductor quantum structures

X. Marie, Th. Amand, P. Renucci +3 more

Summary form only given. The coherence decay of optically excited electronic systems provides one of the most powerful tools to investigate interaction processes of excited states. In semiconductors, the optical coherence phenomena are usually investigated by nonlinear techniques such as four wave mixing (FWM), photon echo, or reflectivity experiments. Exciton-phonon, exciton-exciton, or exciton-free carriers scattering processes have been explored in recent years with these techniques. As demonstrated recently, a direct measurement of the optical dephasing time can be obtained through the temporal coherent control of electronic excitations. In these experiments, the emission following the excitation by an ultrashort optical pulse sequence, is detected in a non-specular direction (secondary emission). This provides an alternative approach to FWM techniques, which allows us to analyse the scattering processes either with phonons or due to mutual collisions. Using the coherent control technique monitored through the secondary emission (SE), we report on the coherent dynamics of excitons in bare quantum wells (QW) and compare it to that of exciton-polaritons in microcavity (MC) embedded quantum wells.

Homogeneous linewidth of quantum well excitons from resonance fluorescence spectra

Daniel Schwedt, Ch. Nacke, H. Stolz +3 more

Abstract We report high resolution measurements of resonance fluorescence spectra of high quality GaAs quantum wells after small bandwidth cw excitation. The resulting spectra can be well described with means of light scattering from a statistically distributed ensemble of three‐level‐systems. Using this model we are able to separate the homogeneous linewidth from the inhomogeneous ensemble response. Thus, we present a simple linear tool for sample characterization.

Section II discusses theory of coherent wave mixing in semiconductors, with emphasis on resonant excitation with only one exciton state. Section III reviews recent experimental investigations of amplitude and phase of coherent wave-mixing resonant with quasi-2d excitons in GaAs quantum wells.
