Electrically tunable liquid-crystal metasurfaces with patterned birefringence and dichroism
Paola Savarese, Sarvesh Bansal, Maria Gorizia Ammendola +7
Light propagation through artificially patterned anisotropic materials, such as dielectric metasurfaces, enables precise control of the spatio-vectorial properties of optical field…
Emission dynamics and spectrum of a nanoshell-based plasmonic nanolaser spaser
Ashod Aradian, Andres Cathey, Karen Caicedo +4
We study theoretically the emission and lasing properties of a single nanoshell spaser nanoparticle, or plasmonic nanolaser, made of an active core (gain material) and a plasmonic…
Measuring the complex orbital angular momentum spectrum and spatial mode decomposition of structured light beams
Alessio D'Errico, Raffaele D'Amelio, Bruno Piccirillo +2
Light beams carrying orbital angular momentum are key resources in modern photonics. In many applications, the ability of measuring the complex spectrum of structured light beams i…
Flat polarization-controlled cylindrical lens based on the Pancharatnam-Berry geometric phase
Bruno Piccirillo, Michela Florinda Picardi, Lorenzo Marrucci +1
The working principle of ordinary refractive lenses can be explained in terms of the space-variant optical phase retardations they introduce, which reshape the optical wavefront cu…
Topological features of vector vortex beams perturbed with uniformly polarized light
Alessio D'Errico, Maria Maffei, Bruno Piccirillo +3
Optical singularities manifesting at the center of vector vortex beams are unstable, since their topological charge is higher than the lowest value permitted by Maxwell's equations…
Interplay between diffraction and the Pancharatnam-Berry phase in inhomogeneously twisted anisotropic media
Chandroth Pannian Jisha, Alessandro Alberucci, Lorenzo Marrucci +1
We discuss the propagation of an electromagnetic field in an inhomogeneously anisotropic material where the optic axis is rotated in the transverse plane but is invariant along the…
Electromagnetic confinement via spin-orbit interaction in anisotropic dielectrics
Alessandro Alberucci, Chandroth Pannian Jisha, Lorenzo Marrucci +1
We investigate electromagnetic propagation in uniaxial dielectrics with a transversely varying orientation of the optic axis, the latter staying orthogonal everywhere to the propag…
Guiding light via geometric phases
Sergei Slussarenko, Alessandro Alberucci, Chandroth P. Jisha +4
Known methods for transverse confinement and guidance of light can be grouped into a few basic mechanisms, the most common being metallic reflection, total internal reflection and…
Surface sensitivity of Rayleigh anomalies in metallic nanogratings
Silvio Savoia, Armando Ricciardi, Alessio Crescitelli +4
Sensing schemes based on Rayleigh anomalies (RAs) in metal nanogratings exhibit an impressive bulk refractive-index sensitivity determined solely by the grating period. However, th…
