The currents have been detected via free-space THz experiments at room temperature. Our experiments prove that Coulomb effects strongly influence injection currents. This becomes most prominently visible when exciting light-hole exciton transitions. At this photon energy we observe a pronounced phase shift of the current transients which is due to oppositely oriented heavy-hole and light-hole type contributions. We are currently developing a microscopic theory based on a 14×14 k.p model in combination with the semiconductor Bloch equations to describe the observed features quantitatively.

In samples of high quality,\r\nintrinsic processes like electron-electron and electron-phonon many particle correlations determine the basic optical and transport properties such as lineshape and ultrafast dynamics. At the same time, intersubband excitations allow\r\nthe direct investigation of dynamical properties of an important model system of many particle physics - the two-dimensional electron gas. We here present a microscopic theory for the intersubband dynamics and absorption.\r\nThe calculation of absorption spectra of MQW systems is in principle composed of two parts: the determination of the polarization in a single quantum well within a density matrix approach as the source of electromagnetic radiation\r\n(Fig. 1a) and the calculation of the generated fields in the geometry of interest (Fig. 1b) within a Green's function approach [3,4]. We will here focus on the so-called single-pass geometry (cf. Fig. 1b, [5])." author: - first_name: Ines full_name: Waldmüller, Ines last_name: Waldmüller - first_name: Jens full_name: Förstner, Jens id: '158' last_name: Förstner orcid: 0000-0001-7059-9862 - first_name: 'Andreas ' full_name: 'Knorr, Andreas ' last_name: Knorr citation: ama: 'Waldmüller I, Förstner J, Knorr A.

Diese mikroskopische Beschreibung\r\nwird durch Kombination eines allgemeinen Dichtematrixansatzes mit speziellen Methoden\r\nzur Auswertung der Maxwellgleichungen wie der zeitaufgelösten Finite-Differenzen-Methode\r\n(FDTD) erreicht. Die Theorie wird auf verschiedene physikalische Situationen angewendet, wie z.B.\r\nLichtausbreitung in Volumenhalbleitern, Interband- und Intersubbandübergänge in Quantenfilmstrukturen\r\nund optische Anregung von Quantenpunkten. Der Fokus liegt dabei auf der Beschreibung der\r\nlinearen und nichtlinearen Antwort des Vielteilchensystems und seiner Ankopplung an das elektromagnetische\r\nFeld. In diesem Zusammenhang wird sowohl die Erzeugung als auch der Zerfall von optischen\r\nAnregungen untersucht, indem verschiedene Kopplungsmechanismen wie Elektron-Phonon-,\r\nElektron-Photon- und Elektron-Elektron-Wechselwirkung berücksichtigt werden.\r\nIm Bereich der linearen Optik, also für Anregung mit geringer Intensität, ermöglicht die Theorie\r\ndie Berechnung von Absorptionsspektren. Verschiedene Effekte in linearer Optik werden in dieser\r\nArbeit untersucht und beschrieben: Linienaufspaltung durch Polaritonen im Volumenmaterial, Zunahme\r\nder Linienbreite bei Intersubbandübergängen verursacht durch Elektron-Elektron- und Elektron-\r\nPhonon-Streuung in einzelnen Quantenfilmen, Bildung einer optischen Bandlücke durch starke radiative\r\nKopplung in Vielfilmstrukturen in Bragg-Geometrie, Phononenseitenbänder verursacht durch\r\nquantenkinetische Effekte in einzelnen Quantenpunkten und schliesslich Superradianz und Interferenzeffekte\r\nin Quantenpunktgittern.\r\nBei nichtlinearer Anregung treten Dichte-Rabiflops als fundamentale Prozesse in allen betrachteten\r\nSystemen auf und können als kohärente Be- und Entvölkerung von quantenmechanischen Zuständen\r\nbeobachtet werden. Der Einfluss von starker Lichtkopplung und verschiedenen Wechselwirkungen\r\nauf dynamische Größen wie die Besetzung wird untersucht. Bei nichtlinearer Propagation, bei\r\nder sich ein starker Lichtpuls über längere Strecken in einem System bewegt, wird selbstinduzierte\r\nVerstärkung der Transmission näher betrachtet. Des weiteren werden von der Coulombwechselwirkung\r\nverursachte nichtlineare Effekte wie exzitoninduziertes Dephasieren in Volumenmaterial und\r\nverschränkte Zustände in Quantenpunkten untersucht, die einen Zusammenbruch der Hartree-Fock-\r\nNäherung darstellen.\r\nZusammenfassend werden in dieser Arbeit verschiedene lineare und nichtlineare optische Effekte\r\nin Halbleiternanostrukturen verschiedener Dimensionalität mit Hilfe einer allgemeinen Theorie, die\r\neinen Dichtematrixansatz mit den Maxwellschen Gleichungen kombiniert, untersucht." author: - first_name: Jens full_name: Förstner, Jens id: '158' last_name: Förstner orcid: 0000-0001-7059-9862 citation: ama: Förstner J.
