Today (September 23, 2018) is the Memorial Day of Nobel Laureate Sir Charles Kuen Kao, the father of broadband, who created optical fibres and used them in telecommunications.
Sir Charles Kuen Kao was born on November 4, 1933, in Shanghai, China. His ancestral home is in nearby Jinzan. He studied Chinese and English and French at the Shanghai International School with his brother at home. Kao's family moved to Hong Kong in 1948. There he received his higher education in 1952 from St. Joseph's College and his bachelor’s degree (BSc) in Electrical Engineering from Woolwich Polytechnic College (University of Greenwich). In 1965 he received his PhD in Harold Barlow Guidance from the University College London as a research student. As an external student under Harold Barlow, a professor at University College London, he worked at the Standard Telecommunication Laboratories (STL) (Telephone Research Center) in Harlow, England.
At the UK-based Standard Telecommunication Laboratories (STL) in the 1960s, Kao and his colleagues pioneered the realization of fibre optics as a telecommunications medium. In 1963, when Kao first joined the Optical Communications research team, he made notes to summarize the background situation and technology available at the time and to identify key individuals involved. To this end, he collected samples from different fibre manufacturers and carefully examined the properties of the bulk glass. Kao's study relied primarily on himself. Contaminants in the material caused high light losses of those fibres. Cao was appointed chairman of the electro-optics research team at STL. He took over SDL's fibreglass telecommunications program in December 1964. Because his supervisor, Karboviak, left to become head of communications at the School of Electrical Engineering at the University of New South Wales (UNSW) in Sydney, Australia.
Kao is a pioneer in the development and use of fibre optics in telecommunications. In the 1960s he developed various methods to combine fibreglass with serials to transfer electronic data. This became a basic requirement for the development of the Internet. Kao is known as the father of broadband. Also known as the father of fibre optics and the father of fibre optic communication. Kao was awarded the 2009 Nobel Prize in Physics for his research on fibreglass communication. Nobel laureate Sir Charles Kuen Kao, who developed and used fibre optics in telecommunications, passed away on September 23, 2018, at the age of 84 in Bradbury Hospice, Hong Kong.
