We investigated the refractive index and extinction coefficient dispersion by spectroscopic ellipsometry from ultraviolet,λ ≈ 0.193 μm,up to mid-infrared,λ ≈ 25 μm spectral region.Studied glasses exhibited large values of linear(n632 ≈ 1.91–2.09) and non-linear refractive index(n2 ≈ 1.20–2.67×10−11 esu),Verdet const.(V632 ≈ 22–33 radT−1m−1) and optical band gap energy(Eg ≈ 3.7–4.1 eV).The materials characterization revealed that BaO substitution by ZnO leads(at constant content of TeO2) to an increase in lin. and nonlin. refractive index as well as Verdet const. while the optical band gap energy decreases.Fiber drawing ability of TeO2–ZnO–BaO glassy system has been demonstrated on 60TeO2–20ZnO–20BaO glass with presented mid-infrared attenuation coefficient.
