Twisted Rainbow Light and Nature‐Inspired Generation of Vector Vortex Beams (Laser Photonics Rev. 16(7)/2022)

Optical Vortices In article number 2200080, Petr Bouchal and Zdeněk reveal the twist of rainbow light demonstrate spiral geometric phase in arc. Experiments are based on self-correlation reflected from thousands falling water drops. The results prove that drops naturally imitate control nematic liquid crystals Pancharatnam–Berry metasurfaces. Light shaping underlying formation is used to generate vector vortices glass microspheres, modulating both dynamic light.
