Abstract
Using reactive pulsed laser deposition, a thin film of erbium-doped oxyfluoride-silicate glass is deposited onto a fused silica substrate. Rib waveguides are fabricated from this film using reactive ion etching. The fabrication and characterisation of these waveguides are summarised. As a result of various characterisation experiments described here, it is concluded that close to stoichiometric transfer of material from the bulk to the film has been achieved. It is concluded, however, that strong quenching mechanisms are present in the film, significantly affecting the magnitude of the 4I 13/2?4I15/2 transition fluorescence lifetime.
