Description
Optical fiber amplifiers are hot! Characterized by low noise and high gain power, these compact, broadband amplifiers promise to revolutionize the field of optical communications by making information technology widely accessible to more of the population. Prepared by six leading professionals in the industry, this comprehensive reference provides you with a solid grounding in this emerging technology, helps you better understand the basic phenomena behind OF amplifiers - and gives you the practical knowledge you need to design and produce your own OF systems. If you're an engineer or researcher in optical communications or a related field, you'll welcome this authoritative guide that provides you with a totally up-to-date review of optical fiber amplifier technology: Overview and related technologies; OF amplifier requirements; Energy states of rare earth ions in condensed materials and optical amplification transitions; Rare earth doped fiber design techniques and the microscopic structure of rare earth doped glasses; Device technology and amplification characteristics. The book also describes the behavior of rare earth ions in amplification, examines the key issues involved in fiber amplification, and highlights the design and material technology of fiber amplifiers. Includes 180 equations and nearly 240 illustrations.
