Fiber Optics: Communication with the Speed of Light

September 30, 2023

Andrew R. Chraplyvy

To date, more than 4 billion kilometers of optical fibers have been installed in the world (approximately the distance between the Earth and the planet Neptune, the farthest planet from Earth). This talk will be an introduction to fiber optic communications, which are the backbone of most communication systems around the world.

Andrew R. Chraplyvy received the B.S. degree in physics in 1972 from Washington University, St. Louis, Missouri, and the M.S. and Ph.D. degrees in physics from Cornell University in 1975 and 1977, respectively. He joined the physics department at General Motors Research Labs in 1977 as a Research Scientist where he studied vibrational modes of gases and impurity modes in solids using ultra-high resolution spectroscopy. Since 1980, he has been with Bell Laboratories, where he has held a number of research and management positions. He holds over 90 patents worldwide in the areas of lightwave systems and fiber optics and has authored hundreds of publications. Along with Bob Tkach, Andrew Chraplyvy invented a new type of optical fiber, NZDF, that is widely deployed in intercontinental and long-haul terrestrial networks. In addition, they are responsible for a number of inventions that greatly increased the capacity and speed of optical networks, in particular the concept of dispersion management of optical nonlinearities. These inventions and technologies are found in most high-capacity optical networks worldwide.
