520 | |a This work assesses the incorporation of dopant ions such as Al<sup>3+</sup>, Ga<sup>3+</sup>, Zr<sup>4+</sup>, Nb<sup>5+</sup>, Ta<sup>5+</sup> and Er<sup>3+</sup> 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 Al<sup>3+</sup> and Ta<sup>5+</sup>, behave similarly. These ions are more efficiently incorporated, assist in the incorporation of Er<sup>3+</sup>, and have the same influence on the fluorescence spectra of Er<sup>3+</sup>. The structural role of these ions appear to be their ability to provide nonbridging oxygens around Er<sup>3+</sup>. The waveguide and lasing characteristics of Er<sup>3+</sup> codoped with Ta<sup>5+</sup> are presented. | ||
