The book offers useful information for both readers unfamiliar with semiconductor lasers, through the introductory parts of each chapter, as well as a state-of-the-art discussion of some of the most advanced semiconductor laser structures, intended for readers engaged in research in this field. This book may also serve as an introduction for the companion volume, Semiconductor Lasers II: Materials and Structures, which presents further details on the different material systems and laser structures used for achieving specific diode laser performance features.
Eli Kapon received his Ph.D. in Physics from Tel Aviv University, Israel, in 1982. He was a Research Fellow at the California Institute of Technology, Pasadena, CA and Member of Technical Staff and District Manager at Bellcore, Red Bank, New Jersey, before assuming his current position of Professor of Physics of Nanostructures at the Swiss Federal Institute of Technology in Lausanne. His research interests have ranged from semiconductor lasers to integrated optoelectronics and, more recently, low-dimensional quantum nanostructures.
The first half of the book presents basic concepts, such as the semiconductor physics needed to understand the operation of lasers, p-n junction theory, alloys, heterostructures, quantum nanostructures, k.p theory, waveguides, resonators, filters, and optical processes. The remainder of the book describes various lasers, including double heterostructure, quantum wire, quantum dot, quantum cascade, vertical-cavity surface-emitting, single-mode and tunable, nitride, group IV, and transistor lasers.
This textbook equips students to understand the latest progress in the research and development of semiconductor lasers, from research into the benefits of quantum wire and quantum dot lasers to the application of semiconductor lasers in fiber-optic communications. Each chapter incorporates reading lists and references for further study, numerous examples to illustrate the theory, and problems for hands-on exploration.
In the first few chapters, the book examines the interplay of charge (polarons) and neutral (excitons) photoexcitations in pi-conjugated polymers, oligomers, and molecular crystals in the time domain of 100 fs–2 ns. Summarizing the state of the art in lasing, the final chapters introduce the phenomenon of laser action in organics and cover the latest optoelectronic applications that use lasing based on a variety of cavities, such as distributed feedback-type cavity.
With contributions from a host of renowned international experts, this book explores the underlying processes in both existing and potential organic optoelectronic applications. It provides a broad overview of the scientific debate in the field of photophysics in organic semiconductors.
In concise, high-def videos, various skills and techniques are demonstrated and explained. These cover topics for the novice, such as mounting and cleaning of optics, as well as for the more advanced learner, such as balanced detection, and lock-in amplifiers.
Various interactive widgets let you simulate the experience of aligning a laser beam to an optical system, aligning an interferometer to get fringes, or adjust a Fabry-Perot cavity while observing the mode spectrum. Other tools help you quickly find the Gaussian beam parameters of your laser from measured beam radii, and to calculate the position of a lens or pair of lenses to mode match a laser to a cavity.
Illusion continues to be a major theme in the book, which provides a comprehensive classification system. There are also sections on what babies see and how they learn to see, on motion perception, the relationship between vision and consciousness, and on the impact of new brain imaging techniques.
