Lead-silicate optical nanowires

Only recently, a technique to manufacture optical fibre nanowires with sufficiently low propagation losses for optical applications has been published. Due to the small surface roughness and high diameter uniformity required to achieve low propagation losses, to date the totality of work in the area has focused on the production of silica optical fibre nanowires. Here we report what we believe to be the first successful fabrication of low-loss compound-glass optical wires
