Stockholm: Three physicists won the 2009 Nobel Prize on Tuesday for work on fibre optics and light sensing that helped unleash the Information Technology revolution.
One of them is the fibre-optic cable, which enables transmission of data at the speed of light, and the other is the digital sensor that is the digital camera’s “electronic eye,” the Nobel jury said.
Kao, who has British and US nationality but has been based in Hong Kong, was awarded half of the prize for groundbreaking achievements in the use of glass fibres for optical communication. The 1966 discovery by Kao, now 75 and retired, means that “text, music, images and video can be transferred around the globe in a split second,” the Nobel jury added.
Boyle, a Canadian-US citizen, and Smith, a 79-year-old American, shared the other half of the prize for inventing an imaging semiconductor circuit — the charge-coupled device (CCD) sensor, which is the “electronic eye” of the digital camera. The CCD, which converts light into electrical signals was invented in 1969, inspired by the photo-electric theory that earned Albert Einstein the 1921 Nobel. “It revolutionised photography, as light could be now captured electronically instead of on film,” the committee said.
