The emerging field of semiconductor quantum optics combines semiconductor physics and quantum optics, with the aim of developing quantum devices with unprecedented performance. In this book researchers and graduate students alike will reach a new level of understanding to begin conducting state-of-the-art investigations. The book combines theoretical methods from quantum optics and solid-state physics to give a consistent microscopic description of light-matter- and many-body-interaction effects in low-dimensional semiconductor nanostructures. It develops the systematic theory needed to treat semiconductor quantum-optical effects, such as strong light-matter coupling, light-matter entanglement, squeezing, as well as quantum-optical semiconductor spectroscopy. Detailed derivations of key equations help readers learn the techniques and nearly 300 exercises help test their understanding of the materials covered. The book is accompanied by a website hosted by the authors, containing further discussions on topical issues, latest trends and publications on the field.

This book could not have been written without the extensive work of many diploma and Ph.D. students in our Theoretical Semiconductor Physics Group at the Philipps-Universit¨ at in Marburg. They have contributed to the f- damental understanding and to many applications in the area of coherent semiconductor optics. The one-dimensional tight-binding model, which is exclusively treated in the present book, has been the basis of many of their diploma and Ph.D. theses. The reader will ?nd references to their results and also their names as authors of the publications listed in the sections “S- gested Reading”. In particular, the authors wish to thank Irina Kuznetsova, who prepared a large number of the ?gures and recalculated the underlying data on the basis of the equations presented in this book in cases where parameters or presentation had to be changed and/or optimized. Someoftheproblems,inparticular,thoseconnectedtothemoreintrod- tory chapters, were solved by Swantje Horst and Joachim Kalden. They made valuable suggestions for improved formulation of the problems and pointed out a number of hints we should give our readers in order to help them with the solutions. Furthermore, we wish to thank all our numerous collaborators, together with whom we have performed research in the area of coherent semiconductor optics in the past and present, for many valuable discussions. In particular, without the close cooperation between experiment and theory this research ?eld would not have advanced to the present level.

This book presents an in-depth discussion of the semiconductor-laser gain medium. The optical and electronic properties of semiconductors, particularly semiconductor quantum-well systems, are analzyed in detail, covering a wide variety of near-infrared systems with or without strain, as well as wide-gap materials such as the group-III nitride compounds or the II-VI materials. The important bandstructure modifications and Coulomb interaction effects are discussed, including the solution of the longstanding semiconductor laser lineshape problem. Quantitative comparisons between measured and predicted gain/absorption and refractive index spectra for a wide variety of semiconductor-laser materials enable the theoretical results to be used directly in the engineering of advanced laser and amplifier structures. A wealth of examples for many different material combinations bestow the book with quantitative and predictive value for a wide variety of applications.

Since Fall of 1993, when we completed the manuscript of our book "Semi­ conductor-Laser Physics" [W.W. Chow, S.W. Koch, and M. Sargent III (Springer, Berlin, Heidelberg, 1994)] many new and exciting developments have taken place in the world of semiconductor lasers. Novel laser and ampli­ fier structures were developed, and others, for example, the VCSEL (vertical cavity surface emitting laser) and monolithic MOPA (master oscillator power amplifier), made the transition from research and development to production. When investigating some of these systems, we discovered instances when de­ vice performance, and thus design depend critically on details of the gain medium properties, e.g., spectral shape and carrier density dependence of the gain and refractive index. New material systems were also introduced, with optical emission wave­ lengths spanning from the mid-infrared to the ultraviolet. Particularly note­ worthy are laser and light-emitting diodes based on the wide-bandgap group-III nitride and II~VI compounds. These devices emit in the visible to ultra-violet wavelength range, which is important for the wide variety of optoelectronic applications. While these novel semiconductor-laser materi­ als show many similarities with the more conventional near-infrared systems, they also possess rather different material parameter combinations. These dif­ ferences appear as band structure modifications and as increased importance of Coulomb effects, such that, e.g., excitonic signatures resulting from the at­ tractive electron-hole interaction are generally significantly more prominent in the wide bandgap systems.

Semiconductor-Laser Physics discusses the underlying physics and operational principles of semiconductor lasers. A semiclassical and a quantum version of the laser theory are presented, including an analysis of single- and multimode operation, instabilities, laser arrays, unstable resonators, and microcavity lasers.

The current technological revolution in the development of computing devices has created a demand for a textbook on the quantum theory of the electronic and optical properties of semiconductors and semiconductor devices. This book successfully fulfills this need. Based on lectures given by the authors, it is a comprehensive introduction for researchers or graduate-level students to the subject. Certain sections can also serve as a graduate-level textbook for use in solid state physics courses or for more specialized courses. The final chapters establish a direct link to current research in semiconductor physics.

This substantially revised second edition of the Quantum Theory of the Optical and Electronic Properties of Semiconductors presents the basic elements needed to understand and engage in research in semiconductor physics. In this edition misprints have been corrected and new and more detailed material has been added. In order to treat the valence-band structure of semiconductors, an introduction to the k.p theory and the related description in terms of the Luttinger Hamiltonian was included. An introductory chapter on mesoscopic semiconductor structures was added which discusses the envelope function approximation and the modification caused by the spatial quantum confinement. In many chapters the results are developed in parallel first for bulk material, and then for quasi-two-dimensional quantum wells, and for quasi-one-dimensional quantum wires. Semiconductor quantum dots are treated in a separate chapter.The discussion of time-dependent and coherent phenomena in semiconductors has been considerably extended by including a section dealing with the theoretical description of photon echoes in semiconductors. After the discussion of semiconductor laser physics, optical bistability, and electroabsorption in semiconductors, a new chapter on magneto-absorption has been added, in which magneto-excitons and magneto-plasmas in two-dimensional systems are discussed. The chapter on electron kinetics due to the interaction with longitudinal-optical phonons has been extended and a discussion on carrier-carrier collisions has been added to the chapter dealing with the semiconductor bloch equations. The material is presented in sufficient detail for graduate students and researchers who have a general background in quantum mechanics.

Semiconductor Quantum Dots presents an overview of the background and recent developments in the rapidly growing field of ultrasmall semiconductor microcrystallites, in which the carrier confinement is sufficiently strong to allow only quantized states of the electrons and holes. The main emphasis of this book is the theoretical analysis of the confinement induced modifications of the optical and electronic properties of quantum dots in comparison with extended materials. The book develops the theoretical background material for the analysis of carrier quantum-confinement effects, introduces the different confinement regimes for relative or center-of-mass motion quantization of the electron-hole-pairs, and gives an overview of the best approximation schemes for each regime. A detailed discussion of the carrier states in quantum dots is presented and surface polarization instabilities are analyzed, leading to the self-trapping of carriers near the surface of the dots. The influence of spin-orbit coupling on the quantum-confined carrier states is discussed. The linear and nonlinear optical properties of small and large quantum dots are studied in detail and the influence of the quantum-dot size distribution in many realistic samples is outlined. Phonons in quantum dots as well as the influence of external electric or magnetic fields are also discussed. Last but not least the recent developments dealing with regular systems of quantum dots are also reviewed. All things included, this is an important piece of work on semiconductor quantum dots not to be dismissed by serious researchers and physicists.

The articles in this book review recent developments in the microscopic theory of optical and electronic semiconductor properties. Many advances in this active field are intimately related to the work of Hartmut Haug and his coworkers. At the occasion of Haug's 60th birthday, a number of current and/or former members of his research team review the current state-of-the-art. Topics include the quantum kinetics of electrons, phonons and photons, coherent optical effects, quantum transport, ballistic motion, microscopic semiconductor laser theory with special emphasis on microlasers, symmetry aspects of laser excited semiconductors, as well as a review of the two-dimensional Wigner crystal in a strong magnetic field. The articles present the material in sufficient detail to be understandable by advanced graduate students and researchers who have a good background in quantum mechanics.
