MIM Structure for optical vortex beam generator at nanoscale level
Denis Garoli, Pierfrancesco Zilio, Yuri Gorodetski +2
Optical beams carrying orbital angular momentum (OAM) can find tremendous applications in several fields. In order to apply these particular beams in photonic integrated devices in…
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 (…
Magnetic Control of Transmission and Helicity of Nano-Structured Optical Beams in Magnetoplasmonic Vortex Lenses
Nicolò Maccaferri, Yuri Gorodetski, Andrea Toma +3
We theoretically investigate the generation of far-field propagating optical beams with a desired orbital angular momentum by using an archetypical magnetoplasmonic tip surrounded…
Helicity locking in light emitted from a plasmonic nanotaper
Denis Garoli, Pierfrancesco Zilio, Francesco De Angelis +1
Surface plasmon waves carry an intrinsic transverse spin, which is locked to its propagation direction. Apparently, when a singular plasmonic mode is guided on a conic surface this…
Beaming of helical light from plasmonic vortices via adiabatically tapered nanotip
Denis Garoli, Pierfrancesco Zilio, Yuri Gorodetski +2
We demonstrate the generation of far-field propagating optical beams with a desired orbital angular momentum by using a smooth optical mode transformation between a plasmonic vorte…
