Offers a comprehensive, updated account of this rapidly advancing field in such a way that it can be used as a textbook and a reference monograph. Although the focus is on physical understanding, engineering applications are also discussed. Coverage includes multichannel lightwave systems, erbium-doped fiber amplifiers, soliton communication systems and much more. Each chapter features an extensive reference list as well as an instructive set of problems.

The most recent design and system applications of OF amplifiers are comprehensively described in this detailed book. With specific focus on the latest telecommunication engineering issues, it reviews all significant properties of optical fiber amplifiers and presents highly accurate models for erbium-, neodymium-, and praseodymium- doped fiver amplifiers.

This book deals with the rare earth elements (REE), which are a series of 17 transition metals: scandium, yttrium and the lanthanide series of elements (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium and lutetium).They are relatively unknown to the wider public, despite their numerous applications and their critical role in many high-tech applications, such as high-temperature superconductors, phosphors (for energy-saving lamps, flat-screen monitors and flat-screen televisions), rechargeable batteries (household and automotive), very strong permanent magnets (used for instance in wind turbines and hard-disk drives), or even in a medical MRI application.This book describes the history of their discovery, the major REE ore minerals and the major ore deposits that are presently being exploited (or are planned to be exploited in the very near future), the physical and chemical properties of REEs, the mineral processing of REE concentrates and their extractive metallurgy, the applications of these elements, their economic aspects and the influential economical role of China, and finally the recycling of the REE, which is an emerging field.

Solitons--waves that do not disperse as they travel through a medium--are the most recent and perhaps the most remarkable development in the revolution in telecommunications technology. When coupled with low loss fibers, semiconductor lasers, and erbium doped fibre amplifiers, solitons can carry--with perfect accuracy and at enormous rates--staggering amounts of information across vast distances. Authored by two leaders in the field, this book offers the best, most comprehensive introduction to soliton behavior in optical fibers available. Topics range from the dielectric fiber to the concept of guiding center (average) solitons to transmission control to modulational instability. Solitons in Optical Communications will be avidly read by students and researchers in optical communications and applied mathematics looking for the definitive survey of the hottest topic in telecommunications engineering.
