Book Description
The book addresses issues associated with physics and technology of injection lasers based on self-organized quantum dots. Fundamental and technological aspects of quantum dot edge-emitting lasers and VCSELs, their current status and future prospects are summarized and reviewed. Basic principles of QD formation using self-organization phenomena are reviewed. Structural and optical properties of self-organized QDs are considered with a number of examples in different material systems. Recent achievements in controlling the QD properties including the effects of vertical stacking, changing the matrix bandgap and the surface density of QDs are reviewed. The authors focus on the use of self-organized quantum dots in laser structures, fabrication and characterization of edge and surface emitting diode lasers, their properties and optimization with special attention paid to the relationship between structural and electronic properties of QDs and laser characteristics. The threshold and power characteristics of the state-of-the-art QD lasers are demonstrated. Issues related to the long-wavelength (1.3-mm) lasers on a GaAs substrate are also addressed and recent results on InGaAsN-based diode lasers presented for the purpose of comparison.

Book Description
Semiconductor lasers using quantum-dots in their active regions have been reported to exhibit significant performance advantages over their bulk semiconductor and quantum-well counterparts namely: low threshold current, high differential gain and highly temperature stable light-current characteristics. This thesis investigates the lasing characteristics of a ridge-waveguide laser containing seven layers of quantum dots as the active region. A summary of the electrical and optical performance data of the heterostructure quantum dot lasers, as well as previously fabricated quantum well lasers, is presented. The motivation of using InAs quantum dots in the active region is to produce near infrared emission for telecommunication applications.

Book Description
The book deals with the physics, operating principles and characteristics of the important quantum well devices, namely, the High Electron Mobility Transistor (HEMT), Resonant Tunneling Diode (RTD), Quantum Well Laser (QWL), Quantum Well Infrared Photodetector (QWIP), Modulator and Switch. The basic physical concepts on which these devices are based are discussed in detail with necessary diagrams and mathematical derivations. The growth of heterostructures, theories and experiments on band offset, theories and experimental results on electron states, optical interaction phenomena, and electron transport are discussed as the background material. Practical aspects and up-to-date developments and applications of the devices are also covered. This book will be of interest to researchers and specialists in the field of Solid State Technology, Optics and Optoelectronics. It can also serve as a textbook for graduate students and new entrants in the exciting field of quantum electronics. This book takes the reader from the introductory stage to the advanced level of the construction, principles of operation, and application of these devices.

Book Description
The semiconductor laser, invented over 50 years ago, has had an enormous impact on the digital technologies that now dominate so many applications in business, commerce and the home. The laser is used in all types of optical fibre communication networks that enable the operation of the internet, e-mail, voice and skype transmission. Approximately one billion are produced each year for a market valued at around $5 billion. Nearly all semiconductor lasers now use extremely thin layers of light emitting materials (quantum well lasers). Increasingly smaller nanostructures are used in the form of quantum dots. The impact of the semiconductor laser is surprising in the light of the complexity of the physical processes that determine the operation of every device. This text takes the reader from the fundamental optical gain and carrier recombination processes in quantum wells and quantum dots, through descriptions of common device structures to an understanding of their operating characteristics. It has a consistent treatment of both quantum dot and quantum well structures taking full account of their dimensionality, which provides the reader with a complete account of contemporary quantum confined laser diodes. It includes plenty of illustrations from both model calculations and experimental observations. There are numerous exercises, many designed to give a feel for values of key parameters and experience obtaining quantitative results from equations. Some challenging concepts, previously the subject matter of research monographs, are treated here at this level for the first time.
