A Tm-doped germanate glass composition comprises GeO2having a concentration of at least 20 mole percent, Tm2O3having a concentration of about 0.001 mole percent to about 2 mole percent, and Ga2O3,having a concentration of about 2 mole percent to about 40 mole percent. The composition can further inc
A Tm-doped germanate glass composition comprises GeO2having a concentration of at least 20 mole percent, Tm2O3having a concentration of about 0.001 mole percent to about 2 mole percent, and Ga2O3,having a concentration of about 2 mole percent to about 40 mole percent. The composition can further include an alkaline earth metal compound selected from the group consisting of MgO, CaO, SrO, BaO, BaF2,MgF2,CaF2,SrF2,BaCl2,MgCl2,CaCl2,SrCl2,BaBr2,MgBr2,CaBr2,SrBr2,and combinations thereof, and having a non-zero concentration of less than about 40 mole percent. The composition can further include an alkali metal compound selected from the group consisting of Li2O, Na2O, K2O, Rb2O, Cs2O, Li2F2,Na2F2,K2F2,Rb2F2,Cs2F2,Li2Cl2,Na2Cl2,K2Cl2,Rb2Cl2,Cs2Cl2,Li2Br2,Na2Br2,K2Br2,Rb2Br2,Cs2Br2and combinations thereof, and having a non-zero concentration of less than about 20 mole percent. The emission bandwidth of the composition in the 1450 nm to 1530 nm range can be varied on the basis of one or more composition ratios. A Tm-doped germanate optical amplifier can amplify optical signals in the S-band region of the electromagnetic spectrum.
