Current research projects

MicroFluid

This project investigates the creation of "lab-on-a-chip" concepts using femto laser material structuring. Here, micro-fluidic channels are being generated through two-photon polymerization and direct material ablation. The aim is to combine micro-fluidic and micro-optical components for real-time drinking-water inspection.

Plasmocom

This EU STREP project unites the leading European research groups in the field of plasmonics. Metal and dielectrical nano-structures for dynamic and active plasmonic and photonic components are being investigated. Using non-linear lithography and nanoimprint technologies the Nanophotonics Group generates plasmonic waveguides with dimensions of only a few hundred nanometers which can be characterized by leak-mode microscopy.

Transregio Special Research Field 37, "microstent with active coating as drainage and ventilation system

NiTi stents with dimension of only a few hundred micrometers are generated and further processed by a modern, highly precise workstation equipped with micro valves for flow control. For the first time, NiTi stents were combined with polymer structures and entire stents, including valve caps, were generated for glaucoma therapy.

QUEST Excellence Cluster – „Centre for Quantum Engeneering and Space-Time Research“

Within the scope of the QUEST Excellence Cluster, a research group for "nanophotonics" was established. The group focuses on plasmonics, the generation and simulation of magnetic and left-handed metamaterials as well as non-linear optics for the efficient generation of optical harmonics in the spectral range < 100 nm.
