Herwig Kogelnik (b. June 2, 1932) is an electrical engineer working in optical communications.
He was born in Graz, Austria and he received his engineering degree from the Technische Hochschule Wien in Vienna, Austria in 1955, and a Doctorate in 1958, also from the Technische Hochschule. In 1960, he received his Ph.D. from Oxford University. His work in optical communications has revolutionize global information movement and management. In 1961 he joined Bell Laboratories in Holmdel, New Jersey, where he was the Director of both the Electronics Research Laboratory and the Photonics Research Laboratory. His research focused on optics, electronics, and communications, including work on holography, photonics, laser resonators, and Gaussian beams. He pioneered the distributed-feedback (DFB) laser in 1971, and worked on the development of practical wavelength-division multiplexing (WDM) led to a groundbreaking dense WDM system, further revolutionizing lightwave communications by expanding capacity and lowering costs.
Dr. Kogelnik was awarded the 2006 National Medal of Technology Laureate in a ceremony in the White House on Friday, July 27, 2007 persented by President Bush, "for his pioneering contributions and leadership in the development of laser, optoelectronics, integrated optics and lightwave communications technology that have been instrumental in driving the growth of the fiber optic communications systems for our nation's infrastructure."
