Optical Amplification

Original language description

Optical amplifiers based on the stimulated emission of radiation paved the way for the global expansion of the high-speed internet, revolutionizing the world of telecommunications. They have further enabled highly efficient, high-power laser tools contributing to many areas of industry, medicine, and other domains. This chapter starts with a description of the erbium-doped fiber amplifier (EDFA) for optical fiber communications in the 1550 nm wavelength region. The structure, components, theory, and optimization issues of EDFAs are discussed and used as an example to describe the basics of numerical modeling of optical amplifiers. We then give a brief description of other rare-earth-doped amplifiers, including praseodymium-doped amplifiers for the 1.3 micrometer band and thulium-doped fiber amplifiers for wavelength ranges below and above the band covered by the EDFAs. Next, technologies of cladding-pumped, high-power fiber amplifiers and lasers, mainly based on ytterbium-doped double-clad fibers, are briefly reviewed before an overview of principles of operation of Raman fiber amplifiers, semiconductor optical amplifiers (SOA), parametric fiber amplifiers, and bismuth-doped fiber amplifiers. Finally, selected applications of optical amplifiers are discussed, namely the maximization of the transmission distance without in-line optical amplifiers, EDFAs for spatial mode division multiplexing in multicore optical fibers, and bidirectional EDFA for precise time and frequency transmission
