Prof. Dr. Bernd Hönerlage is emeritus at the University of Strasbourg and former senior researcher at the CNRS (France). His research focuses on ultrafast dynamics in bulk semiconductors and nano-objects, especially the non-linear optics and time resolved spectroscopy of bulk semiconductor material and nano-crystals. He has more than 30 years of teaching experience in condensed matter and nano-physics.Prof. Dr. Ivan Pelant is senior researcher at the Institute of Physics of The Czech Academy of Sciences and Professor of Quantum Optics and Optoelectronics at Charles University, Prague (Czech Republic). His research focuses on optical properties of semiconductors, non-linear optics, nanostructures and nanophotonics.
