Nano-fabrication and characterization of silicon meta-surfaces provided with Pancharatnam-Berry effect
Pietro Capaldo, Alessia Mezzadrelli, Alessandro Pozzato +3
In this paper, the implementation of optical elements in the form of Pancharatnam-Berry optics is considered. With respect to 3D bulk and diffractive optics, acting on the dynamic…
A versatile quantum walk resonator with bright classical light
Bereneice Sephton, Angela Dudley, Gainluca Ruffato +7
In a Quantum Walk (QW) the "walker" follows all possible paths at once through the principle of quantum superposition, differentiating itself from classical random walks where one…
Nanoporous gold leaves: plasmonic behavior in the visible and mid-infrared spectral regions
Denis Garoli, Gianluca Ruffato, Pierfrancesco Zilio +4
A robust and reproducible preparation of self-standing nanoporous gold leaves (NPGL) is presented, with optical characterization and plasmonic behaviour analysis. Nanoporous gold (…
Electrically-activated spin-controlled orbital angular momentum multiplexer
Gianluca Ruffato, Etienne Brasselet, Michele Massari +1
We present and test the integration of a static orbital angular momentum mode multiplexer with a dynamical geometric-phase optical element enabling on-demand spin-controlled angula…
