The Research Group led by M. Fleischer focuses on the fabrication and optical characterization of specifically engineered plasmonic nanostructures for applications in nano-optics, near-field microscopy, and sensing. The structures are processed by means of thin film metallization, electron beam lithography, nanosphere or nanoimprint lithography, lift-off and/or ion milling. They are investigatd by optical and scanning electron microscopy, Raman spectroscopy, dark field microscopy/spectroscopy, and fluorescence microscopy. The plasmonic nanostructures are furthermore combined with nano-objects (molecules or quantum dots).

With respect to the hν Center, close links exist with the groups of D. Kern (nanostructure fabrication), F. Schreiber (SERS, photovoltaics), T. Chassé/H. Peisert (Raman spectroscopy, resist properties, photovoltaics), A. Meixner/D. Zhang (plasmonics, optical antenna systems, luminescence and near-field investigations), and M. Brecht (nanostructured GRIN lenses). Within LISA+ further collaborations exist with the groups of C. Zimmermann/S. Slama (interaction ultra cold atoms/plasmonic nanostructures) and R. Kleiner/D. Kölle (structured superconducting films).
