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 ... -
Narrowband transmission filters based on resonant waveguide gratings and conformal dielectric-plasmonic coatings
Gallinet, B.; Quaranta, G.; Schneider, C. (2020-11) -
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 ... -
Transmission Microsphere-Assisted Dark-Field Microscopy
Perrin, S.; Li, H. Y.; Badu, K.; Comparon, T.; Quaranta, G.; Messaddeq, N.; et al. (2019)Microsphere-assisted microscopy allows the limit of the diffraction of light to overcome while being non-invasive, full-field, label-free, and easy-to-implement. However, the observation of translucent samples remains ...
