    • Controlling the Color of Plasmonic Substrates with Inkjet Printing 

      Duempelmann, L.; Muller, J. A.; Lutolf, F.; Gallinet, B.; Ferrini, R.; Novotny, L. (2017)
      This study introduces a versatile method for modifying the optical properties of plasmonic substrates by inkjet printing of commercially available, transparent inks with various refractive indices. The large-scale and ...

    • Four-Fold Color Filter Based on Plasmonic Phase Retarder 

      Duempelmann, L.; Luu-Dinh, A.; Gallinet, B.; Novotny, L. (2016)
      We present a plasmonic color filter based on periodic subwavelength silver nanowires, capable of changing the output color by simple rotation of a polarizer. The effect is enabled by a wavelength-dependent phase shift near ...

    • Multispectral Imaging with Tunable Plasmonic Filters 

      Duempelmann, L.; Gallinet, B.; Novotny, L. (2017)
      We present an angle-insensitive, miniaturized and integratable filtering system based on plasmonic substrates for multispectral imaging. Active tunability of the plasmonic filter allows color recording, estimation of unknown ...

    • Optical security features and filters using plasmonic nanostructures 

      Gallinet, B.; Lutolf, F.; Duempelmann, L.; Basset, G.; Luu-Dinh, A.; Schnieper, M.; et al. (2017)
      Plasmonics involves the interaction of light with metallic structures at the nanoscale, which enables in particular the generation of strong reflection and absorption effects in the visible and near infrared range. The ...
