Abstract

The erbium-doped 75TeO₂(25-x)ZnO-xBi₂O₃ glasses have been explored from the density, refractive index, absorption spectra, bandwidth analysis for emission spectra, and lifetime measurements of the ⁴I_13/2 level of Er³⁺ based on Judd-Ofelt and McCumber theories. The effects of bismuth oxide on these three optical parameters Omega_t(t=2, 4, 6) are discussed in terms of the local basic nature of the glass. The results indicate that tellurite bismuth glasses can be used as potential host material for developing broadband optical amplifiers in wavelength-division-multiplexing network system.
