Semiconductor Optics 1

Heinz Kalt studied Physics at the Universities of Bielefeld and Bonn. He earned his doctoral degree in Physics from J.W. Goethe University in Frankfurt/Main in 1985 for a Dissertation (supervised by C. Klingshirn) on laser-induced gratings in CdS. During a postdoc stay at Center for Applied Quantum Electronics of North Texas State University in Denton (USA) he studied high-excitation phenomena and carrier dynamics in III–V semiconductors in the group of A. Smirl. There he also gave his first lecture on semiconductor optics to graduate students. H. Kalt continued his research work at Max Planck Institute for Solid-State Research in the group of W. Rühle and H.J. Queisser and at University Kaiserslautern again with C. Klingshirn. His investigations on optical properties of III–V multi-valley semiconductors formed the basis of his Habilitation Thesis (1993) which was also published in Springer Series in Solid-State Sciences. A second research focus in this time was the understanding of fundamental exciton and pair recombination mechanisms in the search for laser materials for the blue and visible spectral range.In 1994 Heinz Kalt was appointed Professor of Applied Physics at Universität Karlsruhe (TH) (now Karlsruhe Institute of Technology, KIT). Since then his research interest included temporally and spatially resolved optical spectroscopy of semiconductor nano-structures, relaxation and transport dynamics of excitons, high-excitation effects, excitonic spin injection, storage and dynamics,  ZnO nano-rods, random lasing, semiconductor micro-cavities,  artificial organic light-harvesting complexes, optical whispering-gallery resonators, optical bio-sensing, polymer-based flexible photonics, modulation spectroscopy, and novel absorber materials for thin-film solar cells. H. Kalt has (co-)authored more than 350 publications mainly in the field of semiconductor optics.Heinz Kalt served as Dean of the Physics Department at KIT and asDean of Studies of Karlsruhe School of Optics and Photonics (KSOP). He is currently Ombudsperson for good scientific praxis and elected member of the KIT Senate.Claus F. Klingshirn studied Physics at the University of Erlangen finishing his Ph.D. Thesis on ZnO in 1975. He stayed as postdoc at the Laboratoire de Spéctroscopie du Corps Solide in Strasbourg, working on Cu-Halides and ZnO. In 1976 he moved to the Institute of Applied Physics at the University Karlsruhe finishing his Habilitation Thesis in 1980. In 1981 he was appointed Associate Professor at the Institute of Physics at the University in Frankfurt am Main, in 1987 Full Professor at the University in Kaiserslautern and 1993 at the University Karlsruhe, now Karlsruhe Institute of Technology (KIT). In 1986 he spent a sabbatical at the AT&T Bell Labs in Holmdel, in 1996 at Harvard University. In 1995/96 he was also Professeur Invité at the University of Metz. He worked on linear, nonlinear, temporally and spatially resolved spectroscopy of II–VI and III–V SC as bulk materials, quantum wells, islands, dots and nano-rods, on epitaxial growth of II–VI and III–V quantum structures and on nonlinear dynamics, self-oscillations and deterministic chaos in driven systems. He (co)authored over 480 publications in scientific journals, book volumes, conference proceedings and was invited to more than 100 colloquia. Book projects:  C.

Klingshirn (co-)ed. and coauthor. Referee activities for many (inter)national research funding agencies, scientific journals and Member of the boards of international conferences. He served in the academic self-administration as Dean and Dean of Studies of the Physics Department at KIT. Claus Klingshirn retired in 2010.
