Winners of Nobel Prize in Physics, 2009

October 6, 2009 Written by nicolae

This year the Nobel Prize in Physics was awarded to Charles K. Kao "for groundbreaking achievements concerning the transmission of light in fibers for optical communication" and to Willard S. Boyle and George E. Smith "for the invention of an imaging semiconductor circuit – the CCD sensor".

Laser in fibre

Optical fibers are used in transmitting information by means of pulses of light. The light forms an electromagnetic carrier wave modulated by information.
