DOPED OPTICAL WAVEGUIDE AMPLIFIER

摘要

The core of a low phonon energy glass optical fibre is doped with trivalent Dysprosium ions (Dy<3+>) for application as an efficient optical fibre amplifier operating around 1.3 mu m. The device utilises the transition <6>H9/2-<6>F11/2 to <6>H15/2. The low phonon energy (high quantum efficiency) glasses include mixed halides, chalcogenides and chalcohalides. Improvements in efficiency can be achieved by co-doping of the fibre core with Eu<3+> and/or Tb<3+> ions.
