The Principles Of Semiconductor Laser Diodes And Amplifiers

Optical communications technology is growing increasingly in importance, with a rapid pace of development. Innovative optical devices have emerged from the integration of semiconductor laser diodes, amplifiers and filters with optical waveguide technology. This well-researched volume traces the evolution of semiconductor laser amplifiers (SLAs) from these technologies. Focusing on the principle applications of SLAs, the author illustrates the growing importance of these functional components in the future of optical communications systems. This book will provide engineering and science students with a basic understanding of laser diode and optical amplification through the analysis of the performance characteristics of these devices both in theory and application. Practising device engineers wishing to consolidate their knowledge in lightwave technology will also find this book an invaluable reference.

Distributed Feedback Laser Diodes Principles and Physical Modelling H. Ghafouri-Shiraz B. S. K. Lo University of Birmingham, UK Advances in optical fibre-based communications systems have played a crucial role in the development of the information highway. By offering a single mode oscillation and narrow spectral output, distributed feedback (DFB) semiconductor laser diodes offer an excellent optical light source for fibre-based communication systems. This comprehensive text focuses on the basic working principles of DFB laser diodes and details the development of a new technique for enhanced system performance. Considers the optical waveguiding characteristics and properties of semiconductor materials and the physics of DFB semiconductor lasers. Presents a powerful modelling technique based on the transfer matrix method which can be used to improve the design of laser diodes, optical filters and amplifiers. Examines the effect of the various corrugation shapes on the coupling coefficients and lasing characteristics of DFB laser diodes. Technical advice to improve immunity against the spatial hole burning effect. Extensive referencing throughout and a comprehensive glossary of symbols and abbreviations. Distributed Feedback Laser Diodes is an indispensable text for senior students of electrical and electronic engineering and physics, and will consolidate their knowledge in this rapidly growing field. As a technical guide for the structural design of DFB laser diodes, it will serve as an invaluable reference for researchers in optoelectronics, and semiconductor and device physics.

The semiconductor optical amplifier has emerged as an important component in many optical fibre communication, switching and signal processing systems. This invaluable information source provides a comprehensive and detailed treatment of the design and applications of SOAs.

Although semiconductor-diode lasers are the most compact, highest gain and most efficient laser sources, difficulties remain in developing structures that will produce high-quality, diffraction-limited output beams. Indeed, only a few designs have emerged with the potential for producing high-power, high-brightness monolithic sources. This book presents and analyzes the results of work performed over the past two decades in the development of such diode-laser arrays.

This in-depth title discusses the underlying physics and operational principles of semiconductor lasers. It analyzes the optical and electronic properties of the semiconductor medium in detail, including quantum confinement and gain-engineering effects. The text also includes recent developments in blue-emitting semiconductor lasers.
