Paper Abstract

Technology of tellurite glasses from the TeO2-WO3-PbO-La2O3 has been investigated. The effect of lanthanum oxide content on tendency to the crystallization of glassy matrix has been studied. Differential thermal analysis DTA/DSC, XRD measurement have been considered in term of lanthanum oxide influence. The refractive indices (n) for series of glass compositions with various La2O3 contents compared with glass without La2O3 addition has been measured. From obtain results it has been stated that the refractive index slightly increases with the addition of the lanthanum oxides in all glass of compositions. Double crucible drawing technique was applied to drown tellurite optical fibre with high numerical aperture (0.8).
