Nonlinear Optics on Ferroic Materials

Manfred Fiebig completed a degree (Diploma) in physics at the University of Dortmund, Germany, in 1992, obtaining a PhD from the same university in 1996. From 1997 to 1999, he was a JST Research Fellow (Japan Science and Technology) at the University of Tokyo, Dept. of Applied Physics, Japan. In 1999, he returned to the University of Dortmund, where he headed a Junior Research Group until 2001. He was also habilitated at this university in 2001. From 2002 to 2006, Professor Fiebig worked as a DFG (German Research Foundation) Heisenberg Fellow at the Max Born Institute for Non-Linear Optics and Short-Pulse Spectroscopy in Berlin. In 2006, he was appointed Professor of Experimental Solid-State Physics at the University of Bonn, Germany; a position he held until 2011. Since 2011, Manfred Fiebig has been a Professor of Multifunctional Ferroic Materials in the Department of Materials at ETH Zurich where he now heads a group of about 20 people from, presently, 12 different countries. He served as head, resp. deputy head of the Department from 2014-2018. His recent honors include election as APS Fellow, an ERC Advanced Investigator Grant and a three-year appointment as Guest Professor at the Japanese research institute RIKEN.
