dc.description.abstractIn this work, (90-x-y)TeO2-10GeO(2)-(x)Tm2O3-(y)Er2O3 composition of germano-tellurite glasses were synthesized by traditional melting and quenching technique and the spectroscopic properties of synthesized glasses were investigated. The values of Judd-Ofelt (JO) intensity parameters (Omega(t)(t = 2, 4,6)), spontaneous transition probabilities (A), branching ratios (beta) and radiative lifetimes (tau(R)) were obtained by using the Judd-Ofelt (JO) theory and absorption spectra. The stimulated emission cross-sections of TG:Tm and TG:Er glasses in 1.47 mu m and 1.53 mu m wavelength regions were calculated by Fiichtbauer-Ladenburg formula and McCumber theory, respectively. The gain bandwidth-cross section product of TGTm0.5 and TGEr1 glasses was found to be 445.76 x 10(-28) cm(3) and 849 x 10(-28) cm(3), respectively. The fluorescence lifetime measurements were done for the F-3(4) and I-4(13/2) levels to compare with the radiative lifetimes. These results suggest that the TG:Tm and TG:Er studied glasses can potentially possess wider gain bandwidth for S-band amplifier and broadband optical amplifier WDM at 1.53 mu m, respectively.
