Constructing a chiral dipolar mode in an achiral nanostructure
Jörg S. Eismann, Martin Neugebauer, Peter Banzer
We discuss the excitation of a chiral dipolar mode in an achiral silicon nanoparticle. In particular, we make use of the electric and magnetic polarizabilities of the silicon nanop…
Chiroptical response of a single plasmonic nanohelix
Paweł Woźniak, Israel De Leon, Katja Höflich +4
We investigate the chiroptical response of a single plasmonic nanohelix interacting with a weakly-focused circularly-polarized Gaussian beam. The optical scattering at the fundamen…
Mirror-Symmetric Heterogeneous Resonant Nanostructures: Extrinsic Chirality and Spin-Polarized Scattering
Sergey Nechayev, Paweł Woźniak, Martin Neugebauer +2
We investigate a geometrically symmetric gold-silicon sphere heterodimer and reveal its extrinsic chiroptical response caused by the interaction with a substrate. The chiroptical r…
Weak measurement of elliptical dipole moments by C point splitting
Sergey Nechayev, Martin Neugebauer, Martin Vorndran +2
We investigate points of circular polarization in the far field of elliptically polarized dipoles and establish a relation between the angular position and helicity of these C poin…
Transverse Kerker Scattering for Angstrom Localization of Nanoparticles
Ankan Bag, Martin Neugebauer, Paweł Woźniak +2
Angstrom precision localization of a single nanoantenna is a crucial step towards advanced nanometrology, medicine and biophysics. Here, we show that single nanoantenna displacemen…
Tailoring multipolar Mie scattering with helicity and angular momentum
Xavier Zambrana-Puyalto, Xavier Vidal, Pawel Wozniak +2
Linear scattering processes are usually described as a function of the parameters of the incident beam. The wavelength, the intensity distribution, the polarization or the phase ar…
