| 简介 | An optical fiber used for an optical amplifier, is formed by doping glass with rare-earth ions. Both praseodymium ions (Pr+3) and erbium ions (Er+3) are used as the rare-earth ions, and the glass is a fluoride glass or a sulfide glass. The optical fiber can be used at wavelengths of both 1.3 mum and 1.55 mum. The light amplification efficiency of an optical amplifier made of the optical fiber can be improved compared to that of an optical amplifier formed of only Pr+3 or only Er+3. | ||
