Generation of high field enhancement of THz light using Nano-antennas

Date Do, 19.09.2013 - Do, 19.09.2013
Time 10.15
Speaker Salvatore Bagiante, PSI Paul Scherrer Institut, Villigen
Location Universität Bern, Institut für Angewandte Physik, Gebäude exakte Wissenschaften, Hörsaal B116, Sidlerstrasse 5, 3012 Bern
Program THz meta-materials or rather fundament building blocks thereof can be useful, if modified slightly, in a completely different area of research, namely THz science. Recent experiments conducted by Seo and coworkers [1], using a gold film with a single nano-slit, showed that it is possible to significantly enhance the THz field strength inside the gap region. Starting from this investigation we designed and tested a range of nano-structure components. They were built to further enhance the THz field strengths and to allow previously impossible nonlinear THz experiments. In this talk the concept of a nano- antenna and its fabrication process will be introduced and discussed. Moreover, the field enhancement in arrays of nano- slits, split ring resonators, and other sub-wavelength antennas will be shown. 3D electromagnetic simulations as well as sophisticated near-field measurements will be also presented.
