Stephan W. Koch (born 23 May 1953) is a German theoretical physicist. He is professor at the University of Marburg and works on condensed-matter theory, many-body effects, and laser theory. He is best known for his seminal contributions to the optical and electronic properties of semiconductors, semiconductor quantum optics, and semiconductor laser designs. Major portion of his research work has focused on the quantum physics and application potential of semiconductor nanostructures. Besides gaining fundamental insights to the many-body quantum theory, his work has provided new possibilities to develop, e.g., laser technology, based on accurate computer simulations. His objective has been to self-consistently include all relevant many-body effects in order to eliminate phenomenological approximations that compromise predictability of effects and quantum-device designs.
Stephan W. Koch studied physics at the University of Frankfurt, obtained his doctorate 1979 about the theory of electron–hole droplet nucleation in strongly excited semiconductors under the supervision of Prof. Hartmut Haug. During 1981–83, he was a postdoctoral fellow and visiting scientist at the IBM Research, San Jose/California and received habilitation in 1983 about the dynamics of equilibrium and non-equilibrium first-order phase transitions, from the Department of Theoretical Physics of the University of Frankfurt. He continued his active research both in Germany and USA with the help of scholarships from the F. Thyssen Foundation and of the Heisenberg Program of the Deutsche Forschungsgemeinschaft. In 1986, he became professor at the Physics Department and Optical Sciences Center of the University of Arizona in Tucson, AZ, and in 1989, he accepted a chair there. In 1993, he accepted a chair of theoretical physics at the University of Marburg, where he has worked ever since. Stephan W. Koch has very close ties with the research efforts at the Optical Sciences Center, University of Arizona, where he has been an adjunct professor and an active collaborator since 1994.
