Hardcover. Etat : new. Hardcover. Nanometre sized structures made of semiconductors, insulators, and metals and grown by modern growth technologies or by chemical synthesis exhibit novel electronic and optical phenomena due to the confinement of electrons and photons. Strong interactions between electrons and photons in narrow regions lead to inhibited spontaneous emission, thresholdless laser operation, and Bose-Einstein condensation of exciton-polaritons in microcavities. Generation ofsub-wavelength radiation by surface plasmon-polaritons at metal-semiconductor interfaces, creation of photonic band gaps in dielectrics, and realization of nanometer sized semiconductor or insulator structureswith negative permittivity and permeability, known as metamaterials, are further examples in the area of Nanophotonics. The studies help develop spasers and plasmonic nanolasers of subwavelength dimensions, paving the way to use plasmonics in future data centres and high-speed computers working at THz bandwidth with less than a few fJ/bit dissipation.The present book is aimed at graduate students and researchers providing them with an introductory textbook onSemiconductor Nanophotonics. It gives an introduction to electron-photon interactions in Quantum Wells, Wires, and Dots and then discusses the processes in microcavities, photonic band gap materials,metamaterials, and related applications. The phenomena and device applications under strong light-matter interactions are discussed, mostly by using classical and semi-classical theories. Numerous examples and problems accompany each chapter. One of the first comprehensive textbooks dealing with the modern field of Nanophotonics. Though emphasis is given on semiconductors, optical processes in metals and insulators are discussed as well. Provides basic theoretical models in simple terms, and discusses the application areas.

Hardback. Etat : New. Developed from the authors' classroom-tested material, Semiconductor Laser Theory takes a semiclassical approach to teaching the principles, structure, and applications of semiconductor lasers. Designed for graduate students in physics, electrical engineering, and materials science, the text covers many recent developments, including diode lasers using quantum wells, quantum dots, quantum cascade lasers, nitride lasers, group IV lasers, and transistor lasers.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.…
