Alumina aplenty

Brillouin scattering threatens to limit continued power-scaling for many fibre applications, but sapphire-derived all-glass fibres with large concentrations of alumina may help to eliminate this problem. Nature Photonics spoke to Peter Dragic and John Ballato to learn more.

Peter Dragic and colleagues have an Article on sapphire-derived all-glass optical fibres at http://dx.doi.org/10.1038/nphoton.2012.182.
