Our mission is to obtain fundamental control over light-matter interaction by controling the flow of light at the nanometer scale down to the size of single atoms, molecules, and quantum dots.

Our master student Fabian Scheidler
has won the poster prize at the INASCON 2023 conference in Basel
with his poster "Enhanced Second Harmonic Generation
from Silver Nanoantennas"
INASCON 2023
----------------------------------------------------
Second harmonic generation (SHG) is a nonlinear process and is therefore boosted by large field hotspots in plasmonic nanostructures. This was already observed for gold nanoantennas. The project is about to improve SHG in two ways. Firstly, silver is used as the material instead of gold, which reduces material losses in the wavelength range below 500 nm. Secondly, the antenna geometry is designed in such a way that resonances at multiple wavelengths are possible.
