Shaping Field Gradients for Nanolocalization
Sergey Nechayev, Jörg S. Eismann, Martin Neugebauer +1
Deep sub-wavelength localization and displacement sensing of optical nanoantennas have emerged as extensively pursued objectives in nanometrology, where focused beams serve as high…
Substrate-Induced Chirality in an Individual Nanostructure
Sergey Nechayev, René Barczyk, Uwe Mick +1
We experimentally investigate the chiral optical response of an individual nanostructure consisting of three equally sized spherical nanoparticles made of different materials and a…
Mimicking Chiral Light-Matter Interaction
Sergey Nechayev, Peter Banzer
We demonstrate that electric-dipole scatterers can mimic chiral light-matter interaction by generating far-field circular polarization upon scattering, even though the optical chir…
Orbital-to-Spin Angular Momentum Conversion Employing Local Helicity
Sergey Nechayev, Jörg S. Eismann, Gerd Leuchs +1
Spin-orbit interactions in optics traditionally describe an influence of the polarization degree of freedom of light on its spatial properties. The most prominent example is the ge…
Huygens' Dipole for Polarization-Controlled Nanoscale Light Routing
Sergey Nechayev, Jörg S. Eismann, Martin Neugebauer +4
Structured illumination allows for satisfying the first Kerker condition of in-phase perpendicular electric and magnetic dipole moments in any isotropic scatterer that supports ele…
Vectorial vortex generation and phase singularities upon Brewster reflection
René Barczyk, Sergey Nechayev, Abdullah Butt +2
We experimentally demonstrate the emergence of a purely azimuthally polarized vectorial vortex beam with a phase singularity upon Brewster reflection of focused circularly polarize…
