An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light [a] from one end to the other. Such fibers find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than electrical cables.
Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of infrared or visible light through an optical fiber. [1][2] The light is a form of carrier wave that is modulated to carry information. [3] Fiber is preferred over electrical cabling when high bandwidth, long distance, or immunity to ...
Charles K. Kao. Sir Charles Kao Kuen (simplified Chinese: 高锟; traditional Chinese: 高錕; pinyin: Gāo Kūn) GBM KBE FRS FREng [5][6][7][8][9] (November 4, 1933 – September 23, 2018) was a Chinese physicist and Nobel laureate who contributed to the development and use of fibre optics in telecommunications.
Narinder Singh Kapany (31 October 1926 – 4 December 2020) was an Indian-American physicist best known for his work on fiber optics. [2][3][4] Kapany is a pioneer in the field of fiber optics, known for coining and popularising the term. [5][6] Fortune named him one of seven "Unsung Heroes of the 20th Century" for his Nobel Prize -deserving ...
History of optics. Modern ophthalmic lens making machine. Optics began with the development of lenses by the ancient Egyptians and Mesopotamians, followed by theories on light and vision developed by ancient Greek philosophers, and the development of geometrical optics in the Greco-Roman world. The word optics is derived from the Greek term ...
A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used ...
Donald B. Keck (born January 2, 1941) is an American research physicist and engineer most noted for his involvement in developing low-loss optical fiber. Keck grew up in Lansing, Michigan and attended Michigan State University, after which he joined Corning Incorporated ’s research department. As a senior research scientist for Corning, Keck ...
Heinrich Lamm (January 19, 1908 – July 12, 1974), a Jewish German-American physician, was a pioneer in using optical fibers for image transmission, and was the first to make a fiber-optic endoscope. [1] When Lamm was a medical student in 1930, [2] he developed the first flexible fiber-optic bundle capable of transmitting images around curves. [3]
