Abstract A novel co-doping method of multi-rare-earth (RE) ions was demonstrated in tellurite glasses for fiber amplifiers. Fluorescence emissions at both 1.53 and 1.63μm communication windows were firstly observed from Er3+/Yb3+/Tm3+-codoped tellurite glasses under a single wavelength pumping at 980 nm. The full width at half maximum of fluorescence at 1.53 and 1.63μm are 55 nm and 50 nm, respectively. This codoping method of three RE ions could be applied to other low photon energy glasses, which would be possibly used for potential dual wavelength fiber-optic amplifiers to broaden the communication windows.
