The first true introduction to semiconductor optoelectronic devices, this book provides an accessible, well-organized overview of optoelectric devices that emphasizes basic principles. This edition has enhanced readability and depth of coverage with expanded explanations of materials, device phenomena and recent developments in the field. The book's coverage begins with an optionalreview of key concepts such as properties of compound semiconductors, quantum mechanics, semiconductor statistics, carrier transport properties, optical processes and junction theory. The text then gradually progresses to more advanced topics.Features NEW AND ENHANCED FEATURES-Chapter on lightwave networks that reflects the enormous progress in the field of fiber-opticcommunication and the use of optoelectronic devices for this application-Coverage of newer topics Nitrides and visible light emitters New types of modulators New devices such as the quantum cascade laser and the tunneling injection laser-More detailed treatment of Distributed feedback lasers, surface-emitting lasers, avalanche and metal-semiconductor-metalphotodiodes, photo receivers and phototransistors. Transient phenomena and linewidth of lasers-Includes more worked out examples and problems in every chapter to help both readers andinstructors-Chapter Highlights sections to highlight new and attractive portions of each chapter-Features a wealth of valuable appendices as vehicles for more rigorous treatment of selectedsubjects.
