Flexible Physical Unclonable Functions based on non-deterministically distributed Dye-Doped Fibers and Droplets
Mauro Daniel Luigi Bruno, Giuseppe Emanuele Lio, Antonio Ferraro +10
The development of new anti-counterfeiting solutions is a constant challenge and involves several research fields. Much interest is devoted to systems that are impossible to clone,…
Unlocking optical coupling tunability in epsilon-near-zero metamaterials through liquid crystal nanocavities
Giuseppe Emanuele Lio, Antonio Ferraro, Bruno Zappone +6
Epsilon-near-zero (ENZ) metamaterials represent a powerful toolkit for selectively transmitting and localizing light through cavity resonances, enabling the study of mesoscopic phe…
Tailoring of Plasmonic Functionalized Metastructures to Enhance Local Heating Release
Antonio Ferraro, Giuseppe Emanuele Lio, Abdelhamid Hmina +3
Plasmonic nanoheaters are reported that produce a significant local heating when excited by a 532 nm wavelength focussed laser beam. A significant temperature increase derives from…
Hyper Resolute Ultra thin Low Cost All-Dielectric Broadband Achromatic Metalenses
Giuseppe Emanuele Lio, Antonio Ferraro, Tiziana Ritacco +4
Metalenses offer the ground-breaking opportunity to realize highly performing low-weight, flat and ultrathin, optical elements which substantially reduce size and complexity of ima…
Hyper Resolution Two Photon Direct Laser Writing using ENZ Nano-Cavity
Giuseppe Emanuele Lio, Tiziana Ritacco, Antonio Ferraro +3
A novel technique is reported to improve the resolution of two-photon direct laser writing lithography. Thanks to the high collimation enabled by extraordinary (…
Color Tuning by Spontaneous Propagation of Gap Surface Plasmons in Epsilon Near Zero Nano-Cavity
Giuseppe Emanuele Lio, Antonio Ferraro, Michele Giocondo +2
This work presents numerical and experimental results of plasmonic Metal-Insulator optical nano-cavities. The systems are composed of Silver as metal, polyvinylpyrrolidone or indiu…
