Nanophotonics

Prof. Yasuhiko Arakawa and the Walter Schottky Institut (Prof. Gerhard Abstreiter and Prof. Jonathan Finley) work on a joint project in the area of "Si nanophotonics". This project was part of TUM-IAS’ research area "Nanoscience" and was also linked to the cluster of excellence "Nanosystems Initiative Munich". As a Hans Fischer Senior Fellow Prof. Arakawa spent several shorter and longer periods at the Walter Schottky Institut, TUM-IAS and NIM to intensify this collaboration. Two of the doctoral candidates performed part of their research at the home institute of Prof. Arakawa at the University of Tokyo.

Dr. Ulrich Rant aims to design novel bio-nanostructures consisting of biological macromolecules and solid matter. These hybrid-devices are engineered to feature unprecedented functionalities in order to monitor and manipulate physical, chemical, or biological processes on nanometer length scales. During his Carl von Linde Junior Fellowship at TUM, his research focuses (i) on solid-state nanopores to probe bio-molecular interactions on a single-molecule level and (ii) on DNA-templated plasmonic devices to concentrate and manipulate light beyond the diffraction limit.

Prof. Gerhard Abstreiter is a Professor at the TUM Experimental Semiconductor Physics Department I, and was as a Carl von Linde Senior Fellow active in this TUM-IAS Focus Group.
