--- _id: '43413' abstract: - lang: eng text: We describe a novel three-pulse degenerate four-wave mixing configuration that permits the direct observation of the coherence between the σ+ and the σ− exciton states in a GaAs quantum well excited in a two-photon process. It is found that the phase coherence between the two single heavy-hole exciton states decays with a time constant that is considerably longer than the dephasing time of the coherence between these states and the ground state (interband coherence). All the experimental data are well described by numerical solutions of the optical Bloch equations for a phenomenological multilevel model. author: - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: K. full_name: Bott, K. last_name: Bott - first_name: E.J. full_name: Mayer, E.J. last_name: Mayer - first_name: G.O. full_name: Smith, G.O. last_name: Smith - first_name: V. full_name: Heuckeroth, V. last_name: Heuckeroth - first_name: M. full_name: Hübner, M. last_name: Hübner - first_name: J. full_name: Kuhl, J. last_name: Kuhl - first_name: A. full_name: Schulze, A. last_name: Schulze - first_name: M. full_name: Lindberg, M. last_name: Lindberg - first_name: S.W. full_name: Koch, S.W. last_name: Koch - first_name: P. full_name: Thomas, P. last_name: Thomas - first_name: R. full_name: Hey, R. last_name: Hey - first_name: K. full_name: Ploog, K. last_name: Ploog citation: ama: Meier T, Bott K, Mayer EJ, et al.

The field-induced ionization times of the heavy-hole 1s exciton in the miniband field regime are determined from transient four-wave-mixing experiments and theoretical model calculations. They are found to decrease with increasing field, and lie in the picosecond and subpicosecond ranges for fields on the order of a few kV/cm. They are considerably longer than those calculated for a 1s exciton in bulk GaAs. We explain this difference as a result of the nonparabolicities in the superlattice miniband dispersion. In addition to studying the field-induced ionization of the 1s resonance, we also investigate the field dependence of excitonic wave packets composed of both bound and continuum states of the exciton. It is found that the continuum components of the wave packet are more sensitive to low electric fields than the 1s component. © 1996 The American Physical Society. author: - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: G. full_name: von Plessen, G. last_name: von Plessen - first_name: M. full_name: Koch, M. last_name: Koch - first_name: J. full_name: Feldmann, J. last_name: Feldmann - first_name: P. full_name: Thomas, P. last_name: Thomas - first_name: S.W. full_name: Koch, S.W. last_name: Koch - first_name: E.O. full_name: Göbel, E.O. last_name: Göbel - first_name: ' K.W.' full_name: Goosen, K.W. last_name: Goosen - first_name: J.M. full_name: Kuo, J.M. last_name: Kuo - first_name: R.F. full_name: Kopf, R.F. last_name: Kopf citation: ama: Meier T, von Plessen G, Koch M, et al.

Phenomena like Bloch oscillations and negative differential velocity in these structures have been studied using a variety of experimental techniques [1–5]. One particular point of interest has been the transition of the miniband regime to the Bloch oscillation regime with increasing electric field [6,7]. Cw spectra of strongly-coupled superlattices have evidenced that this transition is concomitant with a rapid field-induced ionization of the zero-field miniband exciton [5,8]. While it has been pointed out from the theoretical side that the field-induced ionization process strongly influences the coherent dynamics in the transition region [9], no systematic experimental investigation of the ionization process has been carried out so far. One interesting question that such an investigation could help to answer is to what extent this ionization process differs from the well-documented case of field-induced exciton ionization in bulk semiconductors. author: - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: M. full_name: Koch, M. last_name: Koch - first_name: G. full_name: von Plessen, G. last_name: von Plessen - first_name: J. full_name: Feldmann, J. last_name: Feldmann - first_name: S.W. full_name: Koch, S.W. last_name: Koch - first_name: P. full_name: Thomas, P. last_name: Thomas - first_name: E.O. full_name: Göbel, E.O. last_name: Göbel - first_name: K.W. full_name: Goosen, K.W. last_name: Goosen - first_name: J.M. full_name: Kuo, J.M. last_name: Kuo - first_name: R.F. full_name: Kopf, R.F. last_name: Kopf citation: ama: 'Meier T, Koch M, von Plessen G, et al.

In particular, the energy relaxation of photoexcited carriers has been widely investigated. At the same time, recent progress in the fabrication and characterization of semiconductor heterostructures and superlattices allows a detailed study of a new class of phenomena induced by an applied electric field, such as Bloch oscillations1,2. Both classes of phenomena typically occur on a pico- or femtosecond time-scale, where the coupling between coherent and incoherent phenomena is known to play a dominant role3. Therefore, an adequate theoretical model of the ultrafast dynamics on this time-scale must account for both coherent and incoherent effects on the same kinetic level. author: - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: F. full_name: Rossi, F. last_name: Rossi - first_name: P. full_name: Thomas, P. last_name: Thomas - first_name: S.W. full_name: Koch, S.W. last_name: Koch - first_name: P.E. full_name: Selbmann , P.E. last_name: 'Selbmann ' - first_name: E. full_name: Molinari, E. last_name: Molinari citation: ama: 'Meier T, Rossi F, Thomas P, Koch SW, Selbmann PE, Molinari E.

Extended semiconductor Bloch equations are presented, which include the applied electric field, in addition to the many-body Coulomb contributions in the time-dependent Hartree-Fock approximation. These equations are solved for a one-dimensional tight-binding model of a semiconductor superlattice. Linear and nonlinear optical signals associated with the coherent field-induced effects are calculated. For the case of a static electric field, the influence of the Coulomb interaction, which is treated on the Hartree-Fock level for a contact potential approximation, on the Bloch oscillations, and on their counterpart in the frequency domain, the Wannier-Stark-ladder, is analyzed. For a time-dependent electric field, dynamic localization, i.e., the localization of electrons due to an oscillating electric field, is analyzed. It is predicted that the dynamic localization should be observable in semiconductor superlattices even in the presence of Coulomb interaction. author: - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: G. full_name: von Plessen, G. last_name: von Plessen - first_name: P. full_name: Thomas, P. last_name: Thomas - first_name: S.W. full_name: Koch, S.W. last_name: Koch citation: ama: Meier T, von Plessen G, Thomas P, Koch SW.

The theory generalizes the semiconductor Bloch equations to describe anisotropic structures. The equation for the interband polarization is solved numerically and the carrier‐density dependent optical nonlinearities are computed. Starting from excitonic absorption, with increasing density exciton saturation and the development of gain is observed. The dependence of the gain spectra on structural parameters of the superlattice is discussed. author: - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: K.-C full_name: Je, K.-C last_name: Je - first_name: F. full_name: Rossi, F. last_name: Rossi - first_name: S.W. full_name: Koch, S.W. last_name: Koch citation: ama: Meier T, Je K-C, Rossi F, Koch SW.

The signals for parallel and cross-polarized exciting pulses show pronounced quantum beats with different frequencies corresponding to the heavy/light-hole splitting and the biexciton binding energy, respectively. Comparison of the experimental data with solutions of the optical Bloch equations for a phenomenological model system shows that these features result from strong contributions of the biexcitonic state. The importance of biexcitons to the nonlinear coherent response of the two-dimension exciton is further confirmed by the frequency dependence of the time-integrated four-wave-mixing signal amplitudes measured for the two polarization geometries. author: - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: E.J. full_name: Mayer, E.J. last_name: Mayer - first_name: G.O. full_name: Smith, G.O. last_name: Smith - first_name: V. full_name: Heuckeroth, V. last_name: Heuckeroth - first_name: J. full_name: Kuhl, J. last_name: Kuhl - first_name: K. full_name: Bott, K. last_name: Bott - first_name: A. full_name: Schulze, A. last_name: Schulze - first_name: S.W. full_name: Koch, S.W. last_name: Koch - first_name: P. full_name: Thomas, P. last_name: Thomas - first_name: R. full_name: Hey, R. last_name: Hey - first_name: K. full_name: Ploog, K. last_name: Ploog citation: ama: Meier T, Mayer EJ, Smith GO, et al.

The approach allows a kinetic description of the relevant interaction mechanisms such as intra- miniband and interminiband carrier-phonon scattering processes. The energy relaxation of photoexcited carriers, as well as their vertical transport, is investigated in detail. The effects of the multiminiband nature of the superlattice spectrum on the energy relaxation process are discussed with particular emphasis on the presence of Bloch oscillations induced by an external electric field. The analysis is performed for different superlattice structures and excitation conditions. It shows the dominant role of carrier–polar-optical-phonon interaction in determining the nature of the carrier dynamics in the low-density limit. In particular, the miniband width, compared to the phonon energy, turns out to be a relevant quantity in predicting the existence of Bloch oscillations. author: - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: F. full_name: Rossi, F. last_name: Rossi - first_name: P. full_name: Thomas, P. last_name: Thomas - first_name: S.W. full_name: Koch, S.W. last_name: Koch - first_name: P.E. full_name: Selbmann, P.E. last_name: Selbmann - first_name: E. full_name: Molinari, E. last_name: Molinari citation: ama: 'Meier T, Rossi F, Thomas P, Koch SW, Selbmann PE, Molinari E.

On the basis of a full three-dimensional description of both coherent and incoherent phenomena in anisotropic structures it is found that appropriate applied oscillating fields change the exciton wave function from anisotropic three dimensional to basically two dimensional. This effective-dimension change is caused by dynamic localization which leads to an increase of the exciton binding energy and of the corresponding oscillator strength. author: - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: F. full_name: Rossi, F. last_name: Rossi - first_name: K.-C full_name: Je, K.-C last_name: Je - first_name: J. full_name: Hader, J. last_name: Hader - first_name: P. full_name: Thomas, P. last_name: Thomas - first_name: S.W. full_name: Koch, S.W. last_name: Koch citation: ama: 'Meier T, Rossi F, Je K-C, Hader J, Thomas P, Koch SW.
