Abstract

A lower maximum phonon-energy lead-germanate glass suitable for fibre optic-applications has been achieved by optimizing the glass composition via the Levin-Block concept. Some cladding silicate glasses compatible with the optimized core-glass are identified. These lead to the realization of a new class of rare-earth doped, low-loss, high strength as well as low cost, multicomponent glass optical fibres for fibre device applications. Absorption and emission spectra, together with fluorescent decay times for Tm3+ ions in the glass are present. The reduced maximum phonon-energy of lead-germanates (890 cm in influencing the glass structures and properties is also addressed.
