Paper Abstract

In this paper we report on design and development of three types of the soft oxide glasses devoted to microstructured optical fibers manufacturing. The lead-bismuth glasses are synthesized in three-component oxide system of PbO-Bi2O3- Ga2O3 and in a complex five-component oxide system of SiO2-Ga2O3-Bi2O3-PbO-CdO. The tellurite glasses are synthesized in oxide system of TeO2-WO3-PbO-Na2O-Nb2O5 with various concentration of WO3 (5-38%mol) and PbO (0-18%mol). Measurements of glass transmittance are performed over the range 200nm-10μm. Linear thermal expansion coefficients and characteristic temperatures of glasses are determined based on dilatometer and Leitz heat microscope measurements. A use of Differential Scanning Calorimetry (DSC) method and crystallization tests (isothermal treatment) allows estimating the thermal stability of the glasses and susceptibility to crystallization. As a reference, similar measurements are performed for commercially available lead-silicate glasses SF57 and SF6, which are considered for development of nonlinear microstructured fibres. The glasses with an optimum resistance for devitrification during multiple thermal processing are selected among all developed glasses for further fibre development. We present a method for development of preform and subpreform elements as tubes, capillaries and rods used in the stack-and-draw technique of the fiber manufacture. We report also successful development of subpreform components of microstructured fibers based on selected tellurite and lead-bismuth glasses.
