Abstract:

Development of rare earth doped silica fibre fabrication using MCVD furnace chelate vapor phase delivery is presented. In this study, erbium and aluminium is used as the dopant with precursor erbium (III) tris (2,2,6,6-tetramethyl-3,5-heptanedionate) and aluminium chloride respectively. The preform was designed for 10 layers of SiO₂-P₂O₃ doped silica (clad structure) and 5 layers of SiO₂-Al₂O₃-Er₂O₃ (core structure). Preform is analysed for the properties of layer structure i.e. refractive index profile using preform index profiler and EPMA (SEM-EDX) for dopant distribution. Results show good longitudinal uniformity despite condensation of metal organic precursor during the fabrication process. Maximum incorporation of Er₂O₃ is about 0.1 mole % with 1.5 mole% of Al₂O₃ in the core.
