Leuthold was born in 1966 in Switzerland. He has a Ph.D. degree in physics from Federal Institute of Technology in Zürich for work in the field of integrated optics and all-optical communications. From 1999 to 2004 he was affiliated with Bell Labs, Lucent Technologies in Holmdel, USA, where he performed device and system research with III/V semiconductor and silicon optical bench materials for applications in high-speed telecommunications. From 2004 to 2013 he was a full professor at Karlsruhe Institute of Technology, where he headed the Institute of Photonics and Quantum Electronics and the Helmholtz Institute of Microtechnology. Since March 2013 he has been a full professor at the Swiss Federal Institute of Technology, where he heads the Institute of Electromagnetic Fields.
Leuthold is a fellow of the Optical Society of America and of the Institute of Electrical and Electronics Engineers. When he was a professor at Karlsruhe, he was a member of the Helmholtz Association Think Tank and a member of the Heidelberg Academy of Science. He currently serves on the board of directors of the Optical Society of America. Leuthold has been and is serving the community as general chair and in many technical program committees.
Leuthold interests are in the fields of photonics, terahertz and communications. His current activities are centered around"
