Abstract
The present invention includes an optical fiber amplifier having a core and cladding layer. The core includes Zirconium dioxide (ZrO.sub.2) and a rare earth material. The core may be co-deposited with SiO.sub.2. A co-dopant of Ytterbium (Yb) may also be used. The optical fiber amplifier is well suited for use in the 1300 nm band when pumped with an optical source of appropriate power and frequency.
