Paper Abstract

Double core optical fibre doped with ytterbium was obtained. Low silica glasses without crystallisation effect were presented. The stable glass composition was doped with ytterbium. A set of physical measurements including: DTA, DSC, DL analysis, absorption spectroscopy, visible and infrared absorption edges and thermo-physical properties (thermal stability parameters, refractive index, thermal expansion coefficient, microhardness, density and molar volume) were determined. The absorption bands originated from the ground state to appropriate excited states were observed. Double-crucible drawing technique was applied to obtain double core optical active fibre with NA=0.2. The refractive indexes of core and cladding glasses have been obtained by slight modification of the base glass.
