Journal ArticleDOI
Hypergeometric-Gaussian modes.
TL;DR: A novel family of paraxial laser beams forming an overcomplete yet nonorthogonal set of modes that have a singular phase profile and are eigenfunctions of the photon orbital angular momentum are studied.
Journal ArticleDOI
Label-free sensing of ultralow-weight molecules with all-dielectric metasurfaces supporting bound states in the continuum
Silvia Romano,Gianluigi Zito,Stefania Torino,Giuseppe Calafiore,Erika Penzo,Giuseppe Coppola,Stefano Cabrini,Ivo Rendina,Vito Mocella +8 more
TL;DR: In this paper, an efficient optical sensor based on a photonic crystal metasurface supporting bound states in the continuum is reported, which exploits a normal-to-the-surface optical launching scheme, with excellent interrogation stability and demonstrates alignment-free performances.
Journal ArticleDOI
Surface-Enhanced Raman and Fluorescence Spectroscopy with an All-Dielectric Metasurface
Silvia Romano,Gianluigi Zito,Stefano Managò,Giuseppe Calafiore,Erika Penzo,Stefano Cabrini,Anna Chiara De Luca,Vito Mocella +7 more
TL;DR: In this paper, the possibility of managing surface electromagnetic states mimicking surface-plasmon resonances in terms of spatial localization, high-field intensity, and dispersion characteristics, while avoiding metallic losses is of great interest.
Journal ArticleDOI
Whispering gallery mode microsphere resonator integrated inside a microstructured optical fiber
TL;DR: A novel in-fiber microresonator coupler, which combines a microstructured optical fiber (MOF) and a polystyrene microsphere (PM), embedded into one of its empty capillaries, is reported on.
Journal ArticleDOI
Toward hyperuniform disordered plasmonic nanostructures for reproducible surface-enhanced Raman spectroscopy
C. De Rosa,Finizia Auriemma,C. Diletto,R. Di Girolamo,Anna Malafronte,Pasquale Morvillo,Gianluigi Zito,Giulia Rusciano,Giuseppe Pesce,Antonio Sasso +9 more
TL;DR: The self-assembling of clusters of Au-NPs directed by the phase separation of poly(styrene)-b-poly(methylmethacrylate) block-copolymer (BCP) on indium tin oxide coated glass gives rise to a highly reproducible Surface-Enhanced Raman Scattering (SERS) enhancement factor over the centimeter scale.
