This invaluable look provides a comprehensive treatment of design and applications of semiconductor optical amplifiers (SOA). SOA is an important component for optical communication systems. It has applications as in-line amplifiers and as functional devices in evolving optical networks. The functional applications of SOAs were first studied in the early 1990''s, since then the diversity and scope of such applications have been steadily growing. This is the second edition of a book on Semiconductor Optical Amplifiers first published in 2006 by the same authors. Several chapters and sections representing new developments in the chapters of the first edition have been added. The new chapters cover quantum dot semiconductor optical amplifiers (QD-SOA), reflective semiconductor optical amplifiers (RSOA) for passive optical network applications, two-photon absorption in amplifiers, and, applications of SOA as broadband sources. They represent advances in research, technology and commercial trends in the area of semiconductor optical amplifiers.Semiconductor Optical Amplifier is self-contained and unified in presentation. It can be used as an advanced text by graduate students and by practicing engineers. It is also suitable for non-experts who wish to have an overview of optical amplifiers. The treatments in the book are detailed enough to capture the interest of the curious reader and complete enough to provide the necessary background to explore the subject further.

Optical amplifiers play a central role in all categories of fibre communications systems and networks. By compensating for the losses exerted by the transmission medium and the components through which the signals pass, they reduce the need for expensive and slow optical-electrical-optical conversion. The photonic gain media, which are normally based on glass- or semiconductor-based waveguides, can amplify many high speed wavelength division multiplexed channels simultaneously. Recent research has also concentrated on wavelength conversion, switching, demultiplexing in the time domain and other enhanced functions. Advances in Optical Amplifiers presents up to date results on amplifier performance, along with explanations of their relevance, from leading researchers in the field. Its chapters cover amplifiers based on rare earth doped fibres and waveguides, stimulated Raman scattering, nonlinear parametric processes and semiconductor media. Wavelength conversion and other enhanced signal processing functions are also considered in depth. This book is targeted at research, development and design engineers from teams in manufacturing industry, academia and telecommunications service operators.

This work presents the most recent design and system applications of this rapidly advancing technology. With specific focus on the latest telecommunication engineering aspects, this volume shows how to cut design time and effort dramatically. The book: reviews all significant properties of optical fibre identifiers; presents accurate models for erbium, neodymium- and praseodymium-doped fibre amplifiers and weighs the advantages of fibre amplifier optimization; describes the relevant 800-nm, 980-nm and 1480-nm pump bands for 1500-nm amplifiers and features practical design data; evaluates 1400-nm amplifiers and discussed how significant improvements can be obtained for neodymium- and praseodymium-doped amplifiers.

This book is a printed edition of the Special Issue "Applications of Semiconductor Optical Amplifiers" that was published in Applied Sciences

This volume of trends in optical amplifiers and their applications includes such topics as: progess in optical fibre amplifiers; reliability of high-power pump lasers for erbium-doped fibre amplifiers; and inP-based optical switch array using semiconductor optical amplifiers.
