Although the fibre in question could not conduct electricity, the same technique should work with conductive molecules, which could serve as minute diodes and other circuit components.
Sibling semiconductors are used in light-emitting diodes, solid-state lasers and other technologies that generate heat and light far more precisely and efficiently than conventional welders, torches, ovens and bulbs.
Due to the shortage of blue laser diodes, there are so few that the PS3 launch in Europe and other PAL territories has been scratched for 2006 and pushed back to March 2007.
