Jürg Leuthold received the master degree in Physics (Dipl. Phys. ETH) of the Swiss Federal Institute of Technology (ETH) in Zürich, Switzerland, in 1991. From 1992 to 1998 he was with the Micro- and Optoelectronics Institute of the Swiss Federal Institute of Technology where he also got his Ph.D. degree. In this time he has been involved in the modelling, design and characterization of integrated all-optical devices for high-speed telecommunication applications. After a short postdoc time at Tokyo University in spring 1999, he moved to Bell Labs, Lucent Technologies in Holmdel, where he was affilated from 1999 to June 2004. At Bell Labs he was continuing research on III-V semiconductors for high-speed telecommunication applications and performing system experiments with high-speed components. Since July 1, 2004 he is heading the Institute of Highfrequency and Quantumelectronics at the University of Karlsruhe in Germany.
 Beside his research activities, he is serving the scientific community in different international committees.

Karlsruhe, located in South-West Germany, is said to be one of the warmest places in Germany. It is surrounded by the Black Forest and Alsace. It hosts the headquarters of the German Federal Court and boasts the oldest Technical University in Germany which was founded in 1825. And it is actually at this place that Heinrich Hertz discovered the electromagnetic waves in 1887.
