Erbium

Praise for "Erbium-Doped Fiber Amplifiers: Principles and Applications": "The book is an indispensable reference for researchers, development engineers, and system designers in fiber-optic communications...It will excel as an introductory text in upper-level undergraduate and graduate courses on system applications of fiber optics." - "Optik". "One of the most comprehensive and detailed accounts of the physics and fundamental principles of erbium-doped fiber amplifiers...I do not hesitate to recommend the book enthusiastically to anyone having an interest in EDFAs and their applications." - "Physics Today". Erbium-doped fiber amplifiers are an important technology for lightwave voice, video, and data transmission. The passage of the 1996 Telecommunications Act and the growth of the Internet have sparked intense demand for expanded bandwidth in all network layers, resulting in significant advances in Erbium-Doped Fiber Amplifier (EDFA) technology. This two-volume set combines "Erbium-Doped Fiber Amplifiers: Principles and Applications", an important exploration of the then - infant technology of erbium-doped fiber amplifiers, and "Erbium-Doped Fiber Amplifiers: Device and System Developments", a new volume designed to expands the reader's conceptual understanding of EDFAs and cover the developmental issues of EDFAs that are relevant to modern telecom applications. "Erbium-Doped Fiber Amplifiers: Principles and Applications" illuminates such key areas as: modeling light amplification in Er-doped single-mode fibers; fundamentals of noise in optical fiber amplifiers; photodetection of optically amplified signals; spectroscopic properties of erbium glass fibers; gain, saturation, and noise characteristics of EDFAs; device and system applications of EDFAs. "Erbium-Doped Fiber Amplifiers: Devices and Developments" reviews - new aspects in EDFA modeling, including the standard confined-doping, the transcendental-power-equation, and average-inversion-level models; design concepts for EDFAs in terrestrial and submarine WDM systems; transmission fiber design and dispersion-management techniques for terabit/s systems; amplified submarine-cable systems, including a brief history of submarine-cable communications and the investigation of terabit/s system technologies; advanced concepts in the physics of noise in amplified light, noise figure definitions, entropy, and ultimate capacity limits. Delving into fundamental concepts (including a wealth of previously unpublished materials) as well as important breakthroughs, this much-needed resource will place telecom engineers in a position to take advantage of every aspect in the broad potential of EDFAs. Together, this set sheds light on many new frontiers of knowledge, such as inhomogeneous modeling and nonlinear photon statistics, and demonstrates the many broadening benefits of EDFAs, including their polarization insensitivity, temperature stability, quantum-limited noise figure, and immunity to interchannel crosstalk.
