Charles K. Kao

Charles Kuen Kao (CBE ) (高 锟; * November 4, 1933 in Shanghai) is American- British physicist of Chinese origin. He is a pioneer in the field of fiber optics, for which he was honored in 2009 with the Nobel Prize for Physics.

Career

He studied in England and graduated with honors from. In 1965 he received at Imperial College London his Ph. D. After Kao went to the Standard Telecommunication Laboratories of ITT, in Harlow ( Essex ), where he was director of engineering and research at the optical communication using infrared. There he worked with George Hockham in the field of telecommunication over optical fibers, where he for the first time as data on a conductor transmitted light signals from glass. It Kao noted that the high losses of information are not due to electronic problems, but due to impurities in the glass fibers. He proposed in 1966 as a suitable glass fibers before transmission medium, when it is possible to reduce the losses of 1000 dB / km to 20 dB / km. In the fall of 1970, Corning Glass Works had breached this limit with 17 dB / km.

Later Kao was Vice-Chancellor of the Chinese University of Hong Kong. In 1996 he went into retirement.

On October 6, 2009, he was awarded, together with Willard Boyle and George E. Smith, of the Royal Swedish Academy of Sciences awarded the Nobel Prize in Physics " for his pioneering achievements in the field of light transmission through fiber optics for optical communication ".
