Abstract :
We designed and evaluated a fluoride-based high concentration erbium-cerium codoped fiber amplifier. It is suitable for metropolitan area networks due to faster transient, flatter (unfiltered) gain, smaller footprint, and gain excursion than its silica-based counterpart. A detailed study of its transient dynamics has been performed.
