Abstract
Glasses prepared from high purity starting materials were used for pulling optical waveguide fibre by a double crucible technique. The observed optical loss of the glasses and fibres can be accounted for by absorption bands arising from the presence of traces of transition metal ion impurities and the low energy tails of u.v. absorption bands. The relatively high loss of the fibres is attributed to leaching of impurities from the platinum crucibles.
