Nobel honours ‘masters of light’

Three scientists who corralled light to transform our communications systems share this year’s physics Nobel Prize.
Briton Charles Kao is lauded for his work in helping to develop fibre optic cables, the slender threads of glass that carry phone and net data as light.
Willard Boyle and George Smith, both North Americans, are recognised for their part in the invention of the charge-coupled device, or CCD.
This light detector initiated the digital camera revolution.
The Royal Swedish Academy of Sciences, which administers the prize, said half of the award would go to Kao, who was born in Shanghai, China, in 1933 and holds UK-US citizenship.
It was his insight while working in Britain in the 1960s, said the academy, which allowed researchers to take fibre optics to a new level – to enable these thin cables to transmit light over much longer distances than had previously been possible.
