Huber Tobias Time Correlations in Quantum Dot Emission

In this thesis, I focus on the generation of nonclassical light with InAs quantum dots, specifically, on the role of temporal correlations in the biexciton-exciton cascade with regard to realizing a time-bin entanglement scheme. In this work I used self-assembled InAs quantum dots. The sample we used contains quantum dots embedded into a distributed Bragg reflector cavity, which improves the emission properties of the quantum dots. For entanglement to work in multi-photon experiments one would need a high purity of the exciton photon.

Ali Goker Kondo effect in quantum dots

In this monograph, we investigate the transient currents through a quantum dot in the Kondo regime subject to sudden perturbations. We first present novel numerical algorithms which enable relatively fast calculations. We then employ these algorithms to study the transient current through a quantum dot which is symmetrically coupled to metallic leads and its coupling to the leads is abruptly switched such that the Kondo effect is present in the final state. The timescales for the approach to equilibrium are shown to be the same as the ones when the energy level of the dot is suddenly switched. Finally, we study the transient currents in a quantum dot asymmetrically coupled to metallic leads resulting from the abrupt change of the dot level. We show that for asymmetric coupling, sharp features in the density of states of the leads can induce oscillations in the current through the dot. The amplitude of these oscillations increases as the temperature is reduced and saturates below the Kondo temperature. We discuss the microscopic origin of these oscillations and comment on the possibility for their experimental detection.

Tian Yang, John D. O'Brien Photonic Microcavities and Nanocavities Embedded with InAs Quantum Dots

Photonic microcavity and nanocavity devices with quantum dot active materials combine the strong confinement of photons and the discrete states of electronic carriers. They are promising candidates for small-footprint, high-speed and low-power active optical components, and provide a robust platform for the enhancement of light-matter interactions. This monograph starts with an introduction to the basic concepts of quantum dot active materials and photonic cavity devices, and the potential applications in photonic integrated circuits and quantum information processing. Then the material growth and device fabrication techniques are described. Microdisk lasers and photonic crystal nanocavity lasers with InAs quantum dot active material are presented as two important examples. The lasing behavior's temperature and wavelength dependences are explained by a simple model. The last part of the monograph presents the proposal and demonstration of the first photonic crystal nanocavity edge emitting laser, which is designed for high density planar integration and to achieve high collection efficiency for nanolasers.

Marco Lanzagorta Quantum Radar

This book offers a concise review of quantum radar theory. Our approach is pedagogical, making emphasis on the physics behind the operation of a hypothetical quantum radar. We concentrate our discussion on the two major models proposed to date: interferometric quantum radar and quantum illumination. In addition, this book offers some new results, including an analytical study of quantum interferometry in the X-band radar region with a variety of atmospheric conditions, a derivation of a quantum radar equation, and a discussion of quantum radar jamming.This book assumes the reader is familiar with the basic principles of non-relativistic quantum mechanics, special relativity, and classical electrodynamics. Our discussion of quantum electrodynamics and its application to quantum radar is brief, but all the relevant equations are presented in the text. In addition, the reader is not required to have any specialized knowledge on classical radar theory.Table of Contents: Introduction / The Photon / Photon Scattering / Classical Radar Theory / Quantum Radar Theory / Quantum Radar Cross Section / Conclusions

Michael Gerbracht Optically detected resonances induced by far infrared radiation in quantum wells and quantum dots

Doctoral Thesis / Dissertation from the year 2008 in the subject Physics - Theoretical Physics, grade: 1,0, University of Dortmund (Experimentelle Physik II), language: English, abstract: AbstractPhotoluminescence (PL) and optically detected resonances (ODR) where studied on semiconductor quantum wells and quantum dots. Magnetic fields of up to 33 T where applied to samples at temperatures between 0.25 K and 10 K.In nonmagnetic quantum wells optically detected cyclotron resonance was used to determine basic properties such as effective mass and mobility of GaAs/AlGaAs quantum wells. In CdTe/CdMgTe quantum wells evidence for the singlet and triplet state of the negatively and positively charged exciton was found at high magnetic fields. In a highly n-type doped GaAs/AlGaAs quantum well, signatures of the fractional quantum hall effect were observed in PL and ODR data. Also shake up processes in a variety of quantum wells are discussed.In magnetic quantum wells, cusps in the exciton shift are present at moderate magnetic fields which could be assigned to next nearest neighbor interactions between Mn2+ ion pairs and single ions. Resonances in InGaAs/GaAs quantum dots induced by far-infrared radiation have been observed optically. They were studied in quantum dots with different confinement potential and under a series of tilting angles between sample normal and magnetic field direction. The resonances could be assigned to trion formation due to cyclotron resonance in the wetting...

A distinctive discussion of the nonlinear dynamical phenomena of semiconductor lasers. The book combines recent results of quantum dot laser modeling with mathematical details and an analytic understanding of nonlinear phenomena in semiconductor lasers and points out possible applications of lasers in cryptography and chaos control. This interdisciplinary approach makes it a unique and powerful source of knowledge for anyone intending to contribute to this field of research. By presenting both experimental and theoretical results, the distinguished authors consider solitary lasers with nano-structured material, as well as integrated devices with complex feedback sections. In so doing, they address such topics as the bifurcation theory of systems with time delay, analysis of chaotic dynamics, and the modeling of quantum transport. They also address chaos-based cryptography as an example of the technical application of highly nonlinear laser systems.

Stephan Pröller Scanning Probe Microscopy of InAs/InP Nanowires

Bachelor Thesis from the year 2011 in the subject Physics - Other, grade: 1,0, LMU Munich, language: English, abstract: In this thesis the InAs(111)B surface and III-V semiconductor nanowires are investigated using scanning tunneling microscopy and spectroscopy. The morphology of InAs nanowires grown without gold particle is studied. Radial nanowire heterostructure such as InP core with InAs shell are analyzed and the wurtzite top facet is identified. Furthermore nanowire heterostructures with an InP core and InAs shell with induced stacking faults possibly giving rise to quantum dots, which could be used as quantum dot lasers or for quantum information processing, are investigated. A model is obtained based on morphology analysis and as top facet the wurtzite and are found. Furthermore stacking faults on top of a nanowire are seen. The analysis of the InAs(111)B surface shows the hexagonal pattern. Defects are determined to occur due to missing In atoms in the first layer. Spectroscopy next to those defects indicated no influence on the local electronic structure.
