Broadband 1.5 um emission of erbium doped TeO2 WO3 Nb2O5 glass for potential WDM

Erbium-doped glass showing the wider 1.5-um emission band is reported in a novel oxide system TeO_{2}-WO_{3}-Nb_{2}O_{5} and their thermal stability and optical properties such as absorption, emission spectra, cross-sections and fluorescence lifetime were investigated. Compared with other glass host
