Biography

Ortwin Hess studied physics at the University of Erlangen and the Technical University of Berlin. He obtained the Dipl Phys (MSc) and Dr rer-nat (PhD) degrees at the Technical University of Berlin in 1990 and 1993, respectively. From 1990 to 1992 he has been Research Associate in Edinburgh and spent a Post-Doc at the University of Marburg (1993 - 1994). From 1995 to 2003 Ortwin has been Head of the Theoretical Quantum Electronics Group at the DLR in Stuttgart, Germany. He has a Habilitation in Theoretical Physics at the University of Stuttgart (1997) and became Adjunct Professor in 1998. Since 2001 he is Docent of Photonics at Tampere University of Technology in Finland. Ortwin has been Visiting Professor at Stanford University (1997 - 1998) and the University of Munich (2000 - 2001). Since March 2003 Ortwin holds the Chair of Theoretical Condensed Matter and Optical Physics in the Department of Physics and the Advanced Technology Institute. He is Head of the Theory and Advanced Computation Group.

Research Interests

Ortwin is a theoretical physicist. His research interests are in theoretical condensed matter and optical physics, currently focusing, in particular, on the physics of metamaterials and nanoplasmonics, slow light, ultrafast spatio-temporal dynamics of quantum dot lasers and complex condensed matter systems. Recent interests lie also on soft photonics (dynamic light scattering of nanoparticles in polymer opals, molecular motors) and nano-thermodynamics. Together with his group he has made pioneering contributions to slow light and light storage in metamaterials (the 'trapped rainbow' effect) and complex nanoelectronic materials and on the ultra-fast and spatio-temporal dynamics of semiconductor and quantum dot lasers, quantum fluctuations of lasers and optical amplifiers as well as micro-cavity and optically pumped semiconductor lasers.
