Abstract
Arsenic sulfide (As-S) and arsenic selenide (As-Se) glass optical fibers typically possess extrinsic absorption bands in the infrared wavelength region associated with residual hydrogen and oxygen related impurities, despite using purified precursors. We report a purification process based on the addition of 0.1 wt%tellurium tetrachloride (TeCl4) to the glass. During melting, the chlorine from TeCl4 reacts with the hydrogen impurities to produce volatile products (e.g. HCl) that can be removed by subsequent dynamic distillation. The processing conditions have been modified accordingly to give low H-S (1.5 dB/m) and low H-Se (0.2 dB/m) impurity content.
