Available in PDF, EPUB and Kindle. Book excerpt: The interband cascade laser, based on the type II energy band alignment in the InAs/GaSb material system, has great potential to meet the power and the wall plug efficiency requirements of many Army applications. However, the development of interband cascade lasers has lagged the development of InP-based quantum cascade lasers. These latter devices have recently exhibited high power, room temperature, cw operation at 3.8 m and at longer wavelengths. Only a few groups are working on the interband cascade lasers, and relatively modest progress has been made in advancing their high-temperature performance. In this paper, we describe our efforts to improve the high temperature performance of these sources using epi-sidedown mounting.

Download or read book Intersubband Transitions In Quantum Structures written by Roberto Paiella and published by McGraw Hill Professional. This book was released on 2010-05-05 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in epitaxial growth and nanofabrication technology in the past several years have made it possible to engineer sophisticated semiconductor quantum devices with unprecedented control of their electronic and optical properties. A particularly important class of such devices is based on intersubband transitions, i.e. optical transitions between quantized electronic states in semiconductor heterostructures. Most notably, mid-infrared quantum-well infrared photodetectors (QWIPs) and quantum cascade lasers nowadays offer superior performance for applications such as thermal imaging, spectroscopy, and biochemical sensing, and have recently become commercially available. Intersubband devices also have the potential for a revolutionary impact in the fields of silicon photonics, terahertz sensing, and ultra-high-bandwidth fiber-optic communications, and extensive research is ongoing to fulfill this promise. Joined by an international group of world experts, Paiella describes the basic device physics and applications of intersubband transitions, as well as the more recent and important developments in this exciting area of semiconductor nanotechnology.

Download or read book Spectroscopy of Complex Oxide Interfaces written by Claudia Cancellieri and published by Springer. This book was released on 2018-04-09 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the most recent and compelling experimental results for complex oxide interfaces. The results of this book were obtained with the cutting-edge photoemission technique at highest energy resolution. Due to their fascinating properties for new-generation electronic devices and the challenge of investigating buried regions, the book chiefly focuses on complex oxide interfaces. The crucial feature of exploring buried interfaces is the use of soft X-ray angle-resolved photoemission spectroscopy (ARPES) operating on the energy range of a few hundred eV to increase the photoelectron mean free path, enabling the photons to penetrate through the top layers – in contrast to conventional ultraviolet (UV)-ARPES techniques. The results presented here, achieved by different research groups around the world, are summarized in a clearly structured way and discussed in comparison with other photoemission spectroscopy techniques and other oxide materials. They are complemented and supported by the most recent theoretical calculations as well as results of complementary experimental techniques including electron transport and inelastic resonant X-ray scattering.
Download or read book Photovoltaic and Photoactive Materials written by Joseph M. Marshall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this NATO Advanced Study Institute (ASI) was to present an up-to-date overview of various current areas of interest in the field of photovoltaic and related photoactive materials. This is a wide-ranging subject area, of significant commercial and environmental interest, and involves major contributions from the disciplines of physics, chemistry, materials, electrical and instrumentation engineering, commercial realisation etc. Therefore, we sought to adopt an inter disciplinary approach, bringing together recognised experts in the various fields while retaining a level of treatment accessible to those active in specific individual areas of research and development. The lecture programme commenced with overviews of the present relevance and historical development of the subject area, plus an introduction to various underlying physical principles of importance to the materials and devices to be addressed in later lectures. Building upon this, the ASI then progressed to more detailed aspects of the subject area. We were also fortunately able to obtain a contribution from Thierry Langlois d'Estaintot of the European Commission Directorate, describing present and future EC support for activities in this field. In addition, poster sessions were held throughout the meeting, to allow participants to present and discuss their current activities. These were supported by what proved to be very effective feedback sessions (special thanks to Martin Stutzmann), prior to which groups of participants enthusiastically met (often in the bar) to identify and agree topics of common interest.

This book was released on 2007-09-08 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Want an overview of where the technology of terahertz detection has been going? Here it is. The technology has largely been developed around expensive and bulky femtosecond laser systems but, as described in this book, advances in semiconductor superlattice technology are leading to compact "electronic" sources such as the quantum cascade laser, two-terminal "Gunn" type oscillators and even a THz frequency amplifier. These advances towards electronic (as opposed to optical) THz systems mean that the technology will become portable and much less costly.

Book excerpt: Light and light based technologies have played an important role in transforming our lives via scientific contributions spanned over thousands of years. In this book we present a vast collection of articles on various aspects of light and its applications in the contemporary world at a popular or semi-popular level. These articles are written by the world authorities in their respective fields. This is therefore a rare volume where the world experts have come together to present the developments in this most important field of science in an almost pedagogical manner. This volume covers five aspects related to light. The first presents two articles, one on the history of the nature of light, and the other on the scientific achievements of Ibn-Haitham (Alhazen), who is broadly considered the father of modern optics. These are then followed by an article on ultrafast phenomena and the invisible world. The third part includes papers on specific sources of light, the discoveries of which have revolutionized optical technologies in our lifetime. They discuss the nature and the characteristics of lasers, Solid-state lighting based on the Light Emitting Diode (LED) technology, and finally modern electron optics and its relationship to the Muslim golden age in science. The book’s fourth part discusses various applications of optics and light in today's world, including biophotonics, art, optical communication, nanotechnology, the eye as an optical instrument, remote sensing, and optics in medicine. In turn, the last part focuses on quantum optics, a modern field that grew out of the interaction of light and matter. Topics addressed include atom optics, slow, stored and stationary light, optical tests of the foundation of physics, quantum mechanical properties of light fields carrying orbital angular momentum, quantum communication, and Wave-Particle dualism in action.
