Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2004-06-01 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: A quantum cascade (QC) laser is a specific type of semiconductor laser that operates through principles of quantum mechanics. In less than a decade QC lasers are already able to outperform previously designed double heterostructure semiconductor lasers. Because there is a genuine lack of compact and coherent devices which can operate in the far-infrared region the motivation exists for designing a terahertz QC laser. A device operating at this frequency is expected to be more efficient and cost effective than currently existing devices. It has potential applications in the fields of spectroscopy, astronomy, medicine and free-space communication as well as applications to near-space radar and chemical/biological detection. The overarching goal of this research was to find QC laser parameter combinations which can be used to fabricate viable structures. To ensure operation in the THz region the device must conform to the extremely small energy level spacing range from Æ10-15 meV. The time and expense of the design and production process is prohibitive, so an alternative to fabrication was necessary. To accomplish this goal a model of a QC laser, developed at Worchester Polytechnic Institute with sponsorship from the Air Force Research Laboratory Sensors Directorate, and the General Multiobjective Parallel Genetic Algorithm (GenMOP), developed at the Air Force Institute of Technology, were integrated to form a computer simulation which stochastically searches for feasible solutions.
