"Numerous interesting nonlinear interactions of electronic excitations and electromagnetic pulses occur on timescales of only a few femtoseconds (1 fs = 10-15 s). My group is developing novel methods to generate tailored optical pulses with tunable central frequencies in the spectral range from 0.1 THz (1 THz = 1012 Hz) to >100 THz, peak field strengths on the scale of atomic bonds, and waveforms down to the range of single oscillations of the light field. These pulses are detected by modern time domain spectroscopy with a resolution far below the duration of an optical cycle - similar to an oscilloscope for light. In addition, special THz resonators fabricated by electron beam lithography allow control of electromagnetic fields and nonlinear interactions on subcycle and subwavelength scales."

Location & approach

The campus of the Technical University of Dortmund is located near the freeway junction Dortmund West, where the Sauerland line A45 crosses the Ruhr expressway B1/A40. The Dortmund-Eichlinghofen exit on the A45 leads to the South Campus, the Dortmund-Dorstfeld exit on the A40 leads to the North Campus. The university is signposted at both exits.

The "Dortmund Universität" S-Bahn station is located directly on the North Campus. From there, the S-Bahn line S1 runs every 20 or 30 minutes to Dortmund main station and in the opposite direction to Düsseldorf main station via Bochum, Essen and Duisburg. In addition, the university can be reached by bus lines 445, 447 and 462. Timetable information can be found on the homepage of the Rhine-Ruhr transport association, and DSW21 also offer an interactive route network map.



One of the landmarks of the TU Dortmund is the H-Bahn. Line 1 runs every 10 minutes between Dortmund Eichlinghofen and the Technology Center via Campus South and Dortmund University S, while Line 2 commutes every 5 minutes between Campus North and Campus South. It covers this distance in two minutes.



From Dortmund Airport, it takes just over 20 minutes to get to Dortmund Central Station by AirportExpress and from there to the university by S-Bahn. A wider range of international flight connections is offered by Düsseldorf Airport, about 60 kilometers away, which can be reached directly by S-Bahn from the university's train station.

The facilities of TU Dortmund University are spread over two campuses, the larger Campus North and the smaller Campus South. Additionally, some areas of the university are located in the adjacent "Technologiepark".
