Paper Abstract

Emissions at 1.3µm and mid-infrared region from several rare-earths ions doped into PbO-Bi2O3-Ga2O3 glasses were investigated. Lifetime of the Pr3+:1G4 level was 53µs with a quantum efficiency of 9%. Emission at 2.73µm from Er3+, which is normally quenched in oxide glass, was evident and the lifetime of the upper emission level was approximately 900µs. Thermal stability of PbO-Bi2O3-Ga2O3 glass was considerably improved by adding 10 mole % of GeO2. Doping of Tm3+ and Ho3+ showed potentials for S-band fiber-optic amplification.
