Fabrication and optical characterisation of doped germanosilicate fibres

Taylor, E.R., Ye, C.C., Ault, B.J. and Payne, D.N. (1993) Fabrication and optical characterisation of doped germanosilicate fibres Journal of the American Ceramic Society New Materials for Advanced Solid State Lasers, 329, p. 185. (doi:10.1557/PROC-329-185).

Record type: Article


This work assesses the incorporation of dopant ions such as Al3+, Ga3+, Zr4+, Nb5+, Ta5+ and Er3+ into the core of germanosilicate optical fibres via modified-chemical-vapour deposition plus solution doping fabrication techniques. We find that highly-charged smaller ions, like Al3+ and Ta5+, behave similarly. These ions are more efficiently incorporated, assist in the incorporation of Er3+, and have the same influence on the fluorescence spectra of Er3+. The structural role of these ions appear to be their ability to provide nonbridging oxygens around Er3+. The waveguide and lasing characteristics of Er3+ codoped with Ta5+ are presented.
