Abstract

Gallium-indium fluoride based glasses are one of the lowest phonon energy hosts for Pr-ion doped fibre amplifiers. However, to date the fabrication of low background loss fibres have been proved difficult. In the present investigation, GaF3/InF3 based glasses are prepared under the controlled reactive atmosphere of SF6, HF and N2 gas mixture. The devitrification characteristics of glass samples prepared in a range of reactive-atmospheres (RA) have been studied using differential scanning calorimetry. From the isothermal data, the time-temperature-transformation curves have been compared for various reactive-atmosphere processing (RAP) conditions and, the influence of RAP conditions on the glass stability is discussed. Loss in multimode fibres (similar to 135 µm) drawn from the glass rods processed under RAP conditions are compared as a function of processing conditions. The measured loss values are reported in 0.5 to 2.0 µm wavelength regime.
