Paper Abstract

Erbium doped fiber amplifier have been demonstrated at several wavelengths. The exceptionally broad and intense absorption spectrum of erbium with other rare-earth co-doped fiber is advantage in high power amplifiers and fiber lasers. In order to broaden amplifying band, it is important to modify spectrum properties of erbium doped optical fiber. In this dissertation, erbium with ytterbium, thulium and Lanthanum co-doped fibers were fabricated by MCVD. This paper focus on the influence of concentration and ratio of rare-earth on spectrum properties of fiber. It was found that absorption of the EDFs was affected by erbium concentration and ratio of erbium and other rare-earth. Absorption band were broadened by adding dopant of other rare-earth.
