The professorship of high-frequency engineering at the University of the Federal Armed Forces Hamburg was founded in April 1974. Prof. Dr.-Ing. H.G. Wäßerling was in charge of this discipline until he retired in March 1990. Univ.-Prof. Dr.-Ing. habil. W. Platte was in charge of this professorship since October 1, 1990. This change brought about a shift in research activities to the fields of microwave photonics and optical fiber optoelectronics, a fact that is documented by the change in the professorship title to “High-Frequency Engineering and Optoelectronics”. Teaching and research together have a staff of three research assistants and two technical assistants. Upon reaching the age of 65, Prof. Platte retired on the 1st of February 2008. Univ.-Prof. Dr.-Ing. C.G. Schäffer was in charge of this professorship since July 1, 2009.

All courses offered by this professorship are related to the field of communication engineering witin the advanced-level study of electrical engineering. The compulsory subject of high-frequency engineering / microwave engineering (during the 8th, 9th and 10th trimesters) with its lecture, exercise and laboratory courses covers the classical field of high-frequency engineering: circuits consisting of passive components, transmitter and receiver circuits as well as microwave engineering. To deepen knowledge of subject matters there are optional lecture courses or seminars on optical broadband communication, antennas and antenna systems as well as on microwave and millimeter wave photonics.

The scientific field of the Chair of High-Frequency Engineering is the physical basis of next generation communication systems. This involves the entire range of communications and sensing from 3 MHz up to optical frequencies. The focus of research includes millimeter wave photonics, fiber-optic communications, optical realization of secure communications, photonic biosensing and HFradar systems. At the chair wireless millimeter wave links demonstrated bit-rates up to 10 Gbps transmitted at 80 GHz in 2010. Silicon-photonics based OFDM demultiplexers designed at the Chair enable systems for fiber-optic Tbps links. Optical monitoring technologies allow for the health monitoring of the fiber optic communication infrastructure. The cooperation with external partners is essential for our scientific activities. Among others, important cooperations include the Deutsche Telekom, ADVA optical networking SE, the TU Berlin and the Kurt-Schwabe Institute for Measurement and Sensing Technology.
