  • Abstract
    The origin of the increase in the intensity of OH bands with heat treatment has been investigated using deuterium-containing VAD fibres. Remarkable loss increases only in the absorption peaks due to the OH ions have been observed after 200¿500°C heat treatment applied to three kinds of fibre: drawn from a preform prepared by a D2-O2 flame, and OD-doped in the core and in the cladding. It was confirmed that the origin of the hydrogen causing the loss increase is not in the synthesised glass materials.
