Abstract :
Multicomponent glass fibres with a graded refractive index have been made in the alkali germanosilicate system using the double-crucible method. The index profile is based on Na+ ¿ K+ ion exchange. Bulk-glass absorption losses of ¿10 dB/km at 752 nm have been measured. The present minimum level of fibre attenuation is 35 dB/km.
