Color-Selective and Versatile Light Steering with up-Scalable Subwavelength Planar Optics
Quaranta, G.; Basset, G.; Martin, O. J. F.; Gallinet, B. (2017)Resonant waveguide gratings (RWGs) are subwavelength structures of great interest for biosensors, optical filters and optical security applications. We demonstrate and characterize a beam steering device, where the in ... -
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 ... -
Cylindrical microlensing for enhanced collection efficiency of small pixel SPAD arrays in single-molecule localisation microscopy
Gyongy, I.; Davies, A.; Gallinet, B.; Dutton, N. A. W.; Duncan, R. R.; Rickman, C.; et al. (2018)Single-photon avalanche photodiode (SPAD) image sensors offer time-gated photon counting, at high binary frame rates of >100 kFPS and with no readout noise. This makes them well-suited to a range of scientific applications, ... -
Electrically tunable multicolored filter based on plasmonic nanoscale phase retarder and liquid crystals
Driencourt, L.; Kazazis, D.; Ekinci, Y.; Federspiel, F.; Frantz, R.; Ferrini, R.; Gallinet, B. (2019)An electrically tunable filter based on a nanoimprinted plasmonic phase retarder and liquid crystal cell is reported. A plasmon resonance and its abrupt phase jump yield structural colors between crossed polarizers. A range ... -

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 ... -
Light refocusing with up-scalable resonant waveguide gratings in confocal prolate spheroid arrangements
Quaranta, G.; Basset, G.; Benes, Z.; Martin, O. J. F.; Gallinet, B. (2018)Resonant waveguide gratings (RWGs) are thin-film structures, where coupled modes interfere with the diffracted incoming wave and produce strong angular and spectral filtering. The combination of two finite-length and ... -
Low-Cost and Large-Area Strain Sensors Based on Plasmonic Fano Resonances
Lutolf, F.; Casari, D.; Gallinet, B. (2016)This study presents a strain sensor based on plasmonic Fano resonances. The investigated system consists of U-shaped aluminum nanowires that are fabricated at wafer scale with hot embossing and oblique metal evaporation. ... -
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 ... -
