The University of Karlsruhe (TH), also called Fridericiana, is the oldest technical university in Germany. Up to this day the University is primarily shaped by the technical and natural sciences, and by engineering departments. The University of Karlsruhe, belongs to the three leading German universities with the strongest research activities, and as a matter of fact, if one only accounts for the natural sciences, the University of Karlsruhe has the most support and funds from the German Science Foundation (DFG) nationwide. In total numbers, the University of Karlsruhe has an annual budget of 244 million Euros, hosts 16,900 students of which 4,000 are international students. The University has 11 departments, whereof the Department for Electrical Engineering and Information Technology with 1,700 students is among the biggest.

The Institute of High-Frequency and Quantum Electronicsis one of 14 institutes of the Department for Electrical Engineering and Information Technology. The focus of the institute, with its 22 members, is in the area of photonic communications and microwave applications. The laboratory maintains activities and labs for the design, fabrication and system-level testing of the latest high-speed photonic devices and systems. Current activities are in the fields of high-speed optical telecommunication research in the 10, 40 and 160 Gb/s range, non-linear optical communication research and photonic crystal and nano-photonic device research. The institute maintains software and equipment for state-of-the-art optical chip and network design, as well as CAD programs, in-house fabrication and packaging of optical devices. In addition, measurement setups for telecommunications system level testing up to 160 Gbit/s are available. The leading heads of the Institute of High-Frequency and Quantum Electronics have a strong background in the telecommunications industry, a track record of successful international collaborations and a reputation for research in communications science.

Personnel involved in EURO-FOS

Prof. Jürg Leuthold is currently heading the Institute of High Frequency and Quantum Electronics at the University of Karlsruhe. He received the diploma, degree in physics from the Swiss Federal Institute of Technology (ETH), Zurich, Switzerland, in 1991. In 1992 he joined the Institute of Quantum Electronics of the Swiss Federal Institute of Technology, where he worked in the field of integrated optics and where he also received the Ph.D. degree for contributions in the field of all-optical switching and other integrated optoelectronic components. From 1999 to 2004 he has been affiliated with Bell Labs, Lucent Technologies in Holmdel, USA, where he has been performing device and system research with III/V semiconductor and silicon optical bench materials in few of applications in the high-speed telecommunication field. His research interest are in the areas of high-speed photonic and microwave communications, all-optical devices and high density integrated optics, photonic crystals, modelling and characterization of semiconductor lasers and amplifiers. Prof. J. Leuthold participates in several international technical and scientific committees and is also a member of several national scientific boards.

Dr Stylianos Sygletos obtained his diploma from the department of Electrical Engineering and Computer Science of the National Technical University of Athens. He also did his PhD in the same department on the field of optical communication networks. He has worked for one year as a researcher at the Athens Information Center-AIT, and his is currently a research associate at the Institute of High Frequency and Quantum Electronics-University of Karlsruhe. He has participated in several European research projects (IST-E-Photon/One, IST-DAVID, IST-NOBEL, IST-TRIUMPH, IST-PHOSFOROUS). His expertise is in the area of theoretical modelling and performance evaluation of optical communication systems, with emphasis in the design of high-bit rate multi-wavelength regenerative subsystems, for advanced modulation formats. He has authored and co-authored more than 25 publications in peer reviewed journals and conferences. He is a member of the Technical Chamber of Greece.
