Commemorating 30 years of optical vortices: A comprehensive review

Phys.orgĀ  November 4, 2019
Researchers in China reviewed the 30-year development of the understanding and applications of these intriguing phenomena. The light waves of optical vortices (OVs) are twisted around their direction of travel, with a point of zero intensity at their center. They emphasized that the tunability of OVs includes not only the spectral and temporal tunability but also the OAM-, chirality-, topological-charge-, and singularity-distribution tunability. Prominent applications include sophisticated optical computing processes, novel microscopy and imaging techniques, the creation of ‘optical tweezers’ to trap particles of matter, and optical machining using light to pattern structures on the nanoscale…read more.
