# Strongly directional scattering from dielectric nanowires

## TL;DR

This paper demonstrates that dielectric nanowires can exhibit strongly anisotropic, directional scattering of visible light, which can be controlled by polarization and nanowire shape, advancing nanophotonics applications.

## Contribution

It reveals that dielectric nanowires can produce tunable, strongly directional scattering under various polarizations, extending previous zero-dimensional nanoparticle results.

## Key findings

- Directional scattering occurs in dielectric nanowires under TE or TM illumination.
- Scattering direction can be toggled by rotating incident polarization.
- Shape variation of nanowires further tailors scattering properties.

## Abstract

It has been experimentally demonstrated only recently that a simultaneous excitation of interfering electric and magnetic resonances can lead to uni-directional scattering of visible light in zero-dimensional dielectric nanoparticles. We show both theoretically and experimentally, that strongly anisotropic scattering also occurs in individual dielectric nanowires. The effect occurs even under either pure transverse electric or pure transverse magnetic polarized normal illumination. This allows for instance to toggle the scattering direction by a simple rotation of the incident polarization. Finally, we demonstrate that directional scattering is not limited to cylindrical cross-sections, but can be further tailored by varying the shape of the nanowires.
