Abstract: Polarization gives an additional degree of freedom, that is crucial for structured light applications. The polar-ization state is described by the chirality, shape and orientation of the polarization ellipse. Controlling precisely the chirality can be advantageous for applications involving light-chiral matter interactions [1].

TL;DR: This review presents a comprehensive overview of the theoretical aspects of chirality in light, nanostructures, and nanosystems and their chiroptical interactions and describes the strong intrinsic and extrinsic chiral properties in plasmonic nanoparticle systems.
Tornado waves.
TL;DR: In this article, the authors show that light spiraling like a tornado can be generated by superimposing abruptly auto-focusing ring-Airy beams that carry orbital angular momentum of opposite handedness.

Spiraling light: Generating optical tornados
TL;DR: In this paper , the authors experimentally generate optical tornado waves using spatial multiplexing on a single-phase modulation device and reveal the key factors that lead to angular acceleration, and propose a two-color scheme that makes it possible to generate dynamically twisting light, an optical analog of a drill that can rotate at THz frequencies.
