New Materials for Optical Amplifiers

摘要: Publisher Summary Fiber plays an important role as amplifying medium. The aluminum-doped silica is considered the only commercial host and erbium major dopant. It observed that soluble in Al-silica provides gain at attenuation minimum for transmission fiber. An overview of materials used optical amplification a discussion on application space context devices based these are provided chapter. chapter reviews basic material properties required glasses active methods by which drawn to Furthermore, illustrates device applications. These applications relate principally bandwidth extension power scaling include extended C-band, L-band, band Erbium–Doped Amplifiers (EDFAs), Thulium–Doped (TDFAs) operating S-band, high-power 980 nm ytterbium fiber lasers pumping EDFAs. common systems explored fluorides, alumina-doped silica, antimony-silicates, tellurite.
