Professor Charles K. Kao CBE FRS[2] FREng[3] (Chinese: 高錕; Kao Kuen; born 4 November 1933) is an engineer and a pioneer in the use of fiber optics in telecommunications. Kao, widely regarded as the "Father of Fiber Optic Communications",[4][5][6] was awarded half of the 2009 Nobel Prize in Physics for "groundbreaking achievements concerning the transmission of light in fibers for optical communication".[7]
Biography
He was born in Shanghai (currently Jinshan District of Shanghai) in 1933. His father was a lawyer. His grandfather was Kao Choi-Wan (Gao Chuiwan, 高吹萬), a famous poet, revolutionary, literator, and was a key figure of Nan Society (South Society, 南社) in late Qing Dynasty. His father's uncle was astronomer Ping-Tse Kao (高平子, Kao Crater is named after him). He has a young brother named Kao Woo (高鋙).[8]
Kao's family moved to Hong Kong in 1948. He completed his secondary education at St. Joseph's College in Hong Kong. He then graduated in electrical engineering in 1957 from Woolwich Polytechnic (now the University of Greenwich) but received his degree from University of London and obtained his PhD degree in electrical engineering in 1965, from Imperial College London[9][10][11][12](at that time a constituent college of the University of London).
While studying for his PhD degree, Kao also worked as an engineer for Standard Telephones and Cables (STC) at their Standard Telecommunications Laboratories research centre in Harlow, England (now Nortel Networks).
Kao did his groundbreaking work at STL where he was a young engineer and researcher. Since leaving STL, he has worked as director of research at ITT Corporation.
He joined the Chinese University of Hong Kong in 1970, to found the electrical engineering department. He then went back to ITT during 1970s and worked in United States before served as the university's Vice-Chancellor from 1987 to 1996.[13]
He then worked as the CEO of Transtech. He is currently Chairman and CEO of ITX Services. He resides in Hong Kong as of 2009.
Kao was awarded the Nobel Prize of Physics for his contributions to the study of the transmission of light in fibers for optical communication on October 6, 2009 [14].
Works and related history
In 1966, along with George Hockham, Kao did his pioneering work in the realisation of fiber optics as a telecommunications medium, by demonstrating that the high-loss of existing fiber optics arose from impurities in the glass, rather than from an underlying problem with the technology itself[15]. Kao and his colleagues not only considered the optical physics but also the material properties. Their results were first presented by Kao in early 1966 and further published in June.
Kao concluded that the fundamental limitation for glass light attenuation is below 20 dB/km (Decibels per Kilometer, is a measure of the attenuation of a signal over a distance), which is a key threshold value for optical communications. This conclusion opened the drastic race to find low-loss materials and suitable fibers for such communication.
Kao, together with his new team (members including T.W. Davies, M.W. Jones, and C.R. Wright), pursued this goal by testing various materials. They precisely measured the attenuation of light with different wavelengths in glasses and other materials. During this period, Kao pointed out that the high purity of fused silica (SiO2) made it an ideal candidate for optical communication. This immediately stimulated a worldwide study and production of low-loss glass fibers.[10]
Kao also played a key role in the engineering and commercial realisation of optical communication.
