Abstract
We focus on the research of glasses as mid-infrared optical fiber candidates and investigate the effects of different modifiers on the thermal stability as well as optical and spectroscopic properties of the main composition of 70TeO 2 – 5M x O y – 10P 2 O 5 – 10ZnO – 5PbF 2 in mol%, where M x O y = (modifiers) doped with 2400ppm Er 2 O 3 . The glasses were prepared by the conventional melt quenching method. Thermal characteristics of glasses like the glass transition temperature T g , the temperature for the crystallization onset T x , the maximum crystallization temperature T c, and the thermal stability parameter were determined by DSC method. The ellipsometric data have provided a Sellmeier-type dispersion relations of the refractive index of the investigated glasses. It appears that the quantum efficiency of the 4 I 13/2 → 4 I 15/2 transition is quite high. The absorption and fluorescence spectra have been analyzed in terms of the standard Judd–Ofelt theory along with the photoluminescence decay of the 4 I 13/2 and 4 S 3/2 levels of the Er 3+ ion. The absorption and emission spectra of the 4 I 15/2 ↔ 4 I 13/2 infrared transition have been analyzed within the McCumber theory to yield the peak emission cross-section and figure of merit (FOM) for the amplifier gain.
