Herwig Kogelnik is an Austrian-American electrical and optical engineer. He is best known for his fundamental contributions to the developments in laser technology, optoelectronics, photonics and lightwave communications systems. His work over a 40-year career at Bell Labs earned him the Marconi Prize, the IEEE Medal of Honor, the National Medal of Technology and many other awards. In a series of papers in the early 1960s, he developed the theory of stable optical resonators, which has been fundamental to laser developments ever since. He then turned to the applications of holograms to optical systems, developing with some of his colleagues the basic theory of thick holograms that led to the development of a whole range of optical components, including filters and couplers to integrated optical devices. His innovation was the beginning of the "distributed feedback laser." He also contributed the development of wavelength-division multiplexing.
