Metasurface spaceplates reach a millimeter-scale squeezed length of free space
Imon Kalyan, Raghvendra P. Chaudhary, Nir Shitrit
Metasurfaces offer compact flat lenses (metalenses) for miniaturized imaging systems; however, the utmost miniaturization requires not only metalenses but also a substantial reduct…
Orbit-orbit photonics: Harnessing vortex-trajectory interplay for light manipulation
Raghvendra P. Chaudhary, Imon Kalyan, Nir Shitrit
Light can carry a spin angular momentum, an intrinsic and extrinsic orbital angular momentum, associated with a circular polarization, optical vortex beams, and varying beam trajec…
Dammann Metasurface Route to Overcoming the Uniformity Defects in Two-Dimensional Beam Multipliers
Rinat Gutin, Raghvendra P. Chaudhary, Avraham Reiner +1
Dammann gratings - beam-shaping optical elements acting as beam multipliers with equal-power beams - are a key element in three-dimensional imaging based on structured light and be…
Optical Mode Control by Geometric Phase in Quasicrystal Metasurface
Igor Yulevich, Elhanan Maguid, Nir Shitrit +3
We report on the observation of optical spin-controlled modes from a quasicrystalline metasurface as a result of an aperiodic geometric phase induced by anisotropic subwavelength s…
Photonic transport control by spin-optical disordered metasurface
Dekel Veksler, Elhanan Maguid, Dror Ozeri +3
Photonic metasurfaces are ultrathin electromagnetic wave-molding metamaterials providing the missing link for the integration of nanophotonic chips with nanoelectronic circuits. An…
Weak Measurements of Light Chirality with a Plasmonic Slit
Y. Gorodetski, K. Y. Bliokh, B. Stein +5
We examine, both experimentally and theoretically, an interaction of tightly focused polarized light with a slit on a metal surface supporting plasmon-polariton modes. Remarkably,…
