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 ... -
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 ... -
Microlens testing on back-illuminated image sensors for space applications
Zanella, F.; Basset, G.; Schneider, C.; Luu-Dinh, A.; Fricke, S.; Madrigal, A. M.; et al. (2020-04) -
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 ... -
Steering and filtering white light with resonant waveguide gratings
Quaranta, G.; Basset, G.; Martin, O. J. F.; Gallinet, B. (2017)A novel thin-film single-layer structure based on resonant waveguide gratings (RWGs) allows to engineer selective color filtering and steering of white light. The unit cell of the structure consists of two adjacent ...
