"The book is an indispensable reference for researchers,development engineers, and system designers in fiber-opticcommunications. . . . It will excel as an introductory text inupper-level undergraduate and graduate courses on systemapplications of fiber optics." --Optik"One of the most comprehensive and detailed accounts of the physicsand fundamental principles of erbium-doped fiber amplifiers. . . .I do not hesitate to recommend the book enthusiastically to anyonehaving an interest in EDFAs and their applications." --PhysicsTodayErbium-doped fiber amplifiers are an important technology forlightwave voice, video, and data transmission. The first volume ofErbium-Doped Fiber Amplifiers: Principles and Applications offeredan important exploration of the then-infant technology oferbium-doped fiber amplifiers. The passage of the 1996Telecommunications Act and the growth of the Internet have sparkedintense demand for expanded bandwidth in all network layers,resulting in significant advances in EFDA technology.Erbium-Doped Fiber Amplifiers: Device and System Developmentsbrings telecommunications professionals up to date. Combining thecontributions from four international experts in EDFAs, this newvolume expands the reader's conceptual understanding of EDFAs andcovers the developmental issues of EDFAs that are relevant tomodern telecom applications. The authors review:New aspects in EDFA modeling, including the standardconfined-doping, the transcendental-power-equation, andaverage-inversion-level models Design concepts for EDFAs interrestrial and submarine WDM systems Transmission fiber design anddispersion-management techniques for terabit/s systems Amplifiedsubmarine-cable systems, including a brief history of submarinecable communications and the investigation of terabit/s systemtechnologies Advanced concepts in the physics of noise in amplifiedlight, noise figure definitions, entropy and ultimate capacitylimits Delving into fundamental concepts (including a wealth ofpreviously unpublished materials) as well as importantbreakthroughs, this much-needed resource will place telecomengineers in a position to take advantage of every aspect in thebroad potential of EDFAs.
