“…For the experimental investigations we implement a heterodyne spectral interferometry technique [15] to retrieve polarization-resolved four-wave mixing (FWM) signals. While FWM has often been used to infer exciton dynamics in QWs [16] or for QD ensembles [17], for single QDs the experiments are more challenging because of the weak signal intensity. This longstanding issue has recently been solved by exploiting photonic nanostructures to enhance non-linear responses.…”

A detailed understanding of the population and coherence dynamics in optically driven individual emitters in solids and their signatures in ultrafast nonlinear-optical signals is of prime importance for their applications in future quantum and optical technologies. In a combined experimental and theoretical study on exciton complexes in single semiconductor quantum dots we reveal a detailed picture of the dynamics employing three-beam polarization-resolved fourwave mixing (FWM) micro-spectroscopy. The oscillatory dynamics of the FWM signals in the exciton-biexciton system is governed by the fine-structure splitting and the biexciton binding energy in an excellent quantitative agreement between measurement and analytical description. The analysis of the excitation conditions exhibits a dependence of the dynamics on the specific choice of polarization configuration, pulse areas and temporal ordering of driving fields. The interplay between the transitions in the four-level exciton system leads to rich evolution of coherence and population. Using two-dimensional FWM spectroscopy we elucidate the excitonbiexciton coupling and identify neutral and charged exciton complexes in a single quantum dot. Our investigations thus clearly reveal that FWM spectroscopy is a powerful tool to characterize spectral and dynamical properties of single quantum structures.

“…The experimental results are compared to numerical simulations based on a fully microscopic theory (details of the theory can be found in [12,14,15]). The theory uses a density matrix formulation where a selection of relevant dynamical variables is achieved by invoking the dynamics-controlled truncation (DCT) scheme [14].…”

“…The pulses spectrally cover exclusively the heavy-hole exciton-biexciton system of the quantum-well sample at a photon energy of about E Xhh = 2.808 eV. The intensity of the excitation pulses was kept in a range where processes beyond the χ (3) limit have been shown to play a negligible role for the generation of the wave-mixing signal [9,10,12].…”

“…The coherent optical control of excitonic transitions in semiconductor nanostructures has been a field of intense research over the past decade [1][2][3][4][5][6][7][8][9][10][11][12]. Especially for semiconductor systems an experimental scheme making use of a pair of phase-locked laser pulses has emerged as one of the most favourable techniques since it combines the flexibility required for selectively addressing special resonances with the possibility of an intuitive understanding of the way of action of the coherent-control process in the time domain [3].…”

PACS 42.65. Ky, 78.67.De In experiments and simulations based on a microscopic theory the optical coherent control of excitonbiexciton beats in coherent four-wave-mixing signals from a semiconductor quantum well is demonstrated. It is found that a reduction of the beat amplitude for one four-wave-mixing direction may at the same time coincide with a large beat amplitude for the other direction. The results can be understood by considering that at least two-photon processes are required to coherently excite biexcitonic transitions which are responsible for the occurrence of the beat structure in the four-wave-mixing signals.

A double-cascade-type four-level system of semiconductor multiple quantum wells (MQWs) was constructed with biexcitons and excitons. The nonlinear optical properties for amplification, absorption, and dispersion of 2-weak fields in this scheme are investigated. It shows that the amplification, absorption, and dispersion responses of 2-weak fields can be achieved by appropriately adjusting the relative phase, the probe detuning, and the two control Rabi frequencies. The investigation is much more practical than its atomic counterpart because of its flexible design and the widely adjustable parameters. It may provide a new possibility in technological applications for the light amplifier and optical switch working on quantum coherence effects in MQW solid-state systems.
