Total angular momentum sorting in the telecom infrared with silicon Pancharatnam-Berry transformation optics
Gianluca Ruffato, Pietro Capaldo, Michele Massari +2
Parallel sorting of orbital angular momentum (OAM) and polarization has recently acquired paramount importance and interest in a wide range of fields ranging from telecommunication…
Multiphoton Label-Free ex-vivo imaging using a custom-built dual-wavelength microscope with chromatic aberrations compensation
Andrea Filippi, Giulia Borile, Eleonora Dal Sasso +6
Label-Free Multiphoton Microscopy is a very powerful optical microscopy that can be applied to study samples with no need for exogenous fluorescent probes, keeping the main benefit…
Encoding many channels in the same frequency through radio vorticity: first experimental test
Fabrizio Tamburini, Elettra Mari, Anna Sponselli +5
We have shown experimentally that it is possible to propagate and use the properties of twisted non-monochromatic incoherent radio waves to simultaneously transmit to infinity more…
Multiplication and division of the orbital angular momentum of light with diffractive transformation optics
Gianluca Ruffato, Michele Massari, Filippo Romanato
We present a method to efficiently multiply or divide the orbital angular momentum (OAM) of light beams using a sequence of two optical elements. The key-element is represented by…
Experimental near field OAM-based communication with circular patch array
Fabio Spinello, Elettra Mari, Matteo Oldoni +6
A short range experimental communication system, based on Orbital Angular Momentum (OAM) multiplexing, is presented. We characterize circular arrays of patch antennas designed to t…
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 (…
