Devices treated include semiconductor lasers, optical amplifiers, modulators, wavelength filters and other passives, detectors, all-optical switches, but relevant properties of optical fibres and network aspects are included as well.

Devices treated include semiconductor lasers, optical amplifiers, modulators, wavelength filters and other passives, detectors, all-optical switches, but relevant properties of optical fibres and network aspects are included as well.

The book covers all essential elements of current and next generation fibre optic networks, including many that are ignored in other books. The reader gains an in-depth understanding of the current and future capabilities of fibre optic communication networks. He can estimate what fibre optics has to provide and where its (current and long-term) limitations may lie. Optoelectronic devices and glass fibres are the basis of contemporary communication systems. The book deals with the various components of these systems such as lasers, amplifiers, modulation devices, converters, optical switches, filters, detectors, emitters, sensors and fibre transfer systems. A systematic evaluation of the state of the art in related technological research and the level reached in application is given.

The book gives an in-depth description of the key devices of current and next generation fibre optic communication networks. In particular, the book covers devices such as semiconductor lasers, optical amplifiers, modulators, wavelength filters, and detectors but the relevant properties of optical fibres as well. The presentations include the physical principles underlying the various devices, the technologies used for the realization of the different devices, typical performance characteristics and limitations, and development trends towards more advanced components are also illustrated. Thus the scope of the book spans relevant principles, state-of-the-art implementations, the status of current research and expected future components.

Modern communication technologies have revolutionized society and econ­ omy on a global scale, and progress in this field is still breathtaking. Among the crucial features of these developments is the possibility to transmit/receive ever-increasing bit rates at lower and lower cost. This is due to some ex­ tent to improved electronics, but it is much more due to the capabilities of opticaL fibre-based communication systems. Optical communication tech­ nologies were initially introduced in order to improve traditional information exchange, but they have recently become a key prerequisite for the tremen­ dous growth in internet traffic, and optical technologies will be even more important in enabling and supporting the future expansion of internet traffic with annual growth rates forecast at 100%-200%. It is the purpose of the present book to describe the enabling components of optical communication systems, in particular their fundamentals, principles and current status, as well as the potential for future developments. Following such a scheme, it is the editors'' hope that this book will not only attract the attention of experts already working in the field, but be, at least, likewise directed to interested newcomers. The book is organized into eleven chapters addressing the essential optical and optoelectronic components which form the hardware basis of today''s, and most likely of future, optical networks.
