Rather than trying to merge flat chips with round optical fibres, the team of scientists used high-pressure chemistry techniques to deposit semiconducting materials layer by layer directly into tiny holes in optical fibres. This bypasses the need to integrate fibre-optics onto a chip, and means that the data signal never has to leave the fibre.

Meanwhile, researchers at the Massachusetts Institute of Technology announced in Novemebr that they had developed photonic chips that use light beams rather than electrons. The arrival of photonic computers could help speed traffic across fibre optic networks by eliminating a conversion process, the researchers said.
