ERC-Grant: Functional extreme nonlinear nanomaterials
Metasurfaces that mimic artificial order in the matter have recently opened an exciting gateway to reach unprecedented properties and functionality for the modification of light propagation. The artificial “atoms” and “molecules” of the metasurface can be tailored in shape and size, the lattice constant and inter-atomic interaction can be precisely ...

Topological phase controlled nonlinear optical processes at metasurfaces
Nanostructured surfaces for optical applications gained recently much interest due to their high potential for applications and the simple fabrication methods that are compatible with standard CMOS technology. In our previous work we demonstrated that nanostructured surfaces, so-called metasurfaces, can provide a topological (Berry) phase for ...

TRR 142 - Plasmonic nano-antenna enhanced nonlinear light emission and frequency conversion in dielectric and semiconductor micro-structures (A05)
The project deals with the enhancement of the weak light-matter interaction for nonlinear optical processes. Resonant excitation of coherent electron oscillations in metallic nanostructures can lead to strong field enhancements due to an antenna effect for the photons. With a suitable spatial arrangement of such antennas, even a kind of phase ...

SPP 1391 - Coupling mediated coherent control of localized plasmonic resonances
A direct control of the light matter interaction and therefore the modification of the light propagation is a major challenge in optical research. With our project we want to explore the possibilities of coherently controlled light-matter interaction in plasmonic metamaterials with the goal of modifying the light propagation and nonlinear light ...
