Semiconductor Laser

This book covers the device physics of semiconductor lasers in five chapters written by recognized experts in this field. The volume begins by introducing the basic mechanisms of optical gain in semiconductors and the role of quantum confinement in modern quantum well diode lasers. Subsequent chapters treat the effects of built-in strain, one of the important recent advances in the technology of these lasers, and the physical mechanisms underlying the dynamics and high speed modulation of these devices. The book concludes with chapters addressing the control of photon states in squeezed-light and microcavity structures, and electron states in low dimensional quantum wire and quantum dot lasers. 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.

Physics of Optoelectronic Devices offers readers a broad ranging, systematic review of important topics in semiconductor electronics, physics, and electromagnetics, information essential to understanding the design and operation of optoelectronic devices. The book begins with a detailed look at fundamentals such as Maxwell's equations and semiconductor physics, then explores a vast array of theoretical issues concerning the propagation, generation, modulation, and detection of light. It clearly demonstrates how these issues apply to the operation of various bulk and quantum-well semiconductor devices. Topics and devices discussed include: Heterojunctions and band structure calculations near the band edges for both bulk and quantum-well semiconductors Optical dielectric waveguide theory applied to semiconductor lasers, directional couplers, and electrooptic modulators General theory for optical gain and absorption via interband and intersubband transitions in bulk and quantum-well semiconductors Double heterojunction semiconductor lasers, strained quantum-well lasers, distributed-feedback lasers, and vertical-cavity surface-emitting lasers High-speed modulation of semiconductor lasers using linear and nonlinear gains and the linewidth enhancement theory Franz-Keldysh effects and excitonic effects in bulk and quantum-well semiconductors, electroabsorption modulators Interband and intersubband photodetectors Comprehensive, timely, and practical, Physics of Optoelectronic Devices is both a superior textbook for advanced courses in electrical engineering, applied physics, and materials science and an invaluable reference for professionals.

Solid-state laser - A solid-state laser is a laser that uses a gain medium that is a solid, rather than a liquid such as dye lasers or a gas such as gas lasers. Semiconductor-based lasers are also in the solid state, but are generally considered separately from solid-state lasers (see semiconductor laser).

Laser diode - A laser diode is a laser where the active medium is a semiconductor similar to that found in a light-emitting diode. The most common and practical type of laser diode is formed from a p-n junction and powered by injected electrical current.

Quantum dot laser - A quantum dot laser succeeds in minimizing temperature-sensitive output fluctuations, something not possible with previous semiconductor lasers. Fujitsu and the University of Tokyo have developed a 10 Gbit/s quantum dot laser not affected by temperature, for use in optical data communications and optical networks.

Excimer laser - An excimer laser is a form of ultraviolet chemical laser which is commonly used in eye surgery and semiconductor manufacturing.
