摘要

Abstract

Thirty years ago

Coullet et al. proposed that a special optical field exists in laser cavities bearing some analogy with the superfluid vortex. Since then

optical vortices have been widely studied

inspired by the hydrodynamics sharing similar mathematics. Akin to a fluid vortex with a central flow singularity

an optical vortex beam has a phase singularity with a certain topological charge

giving rise to a hollow intensity distribution. Such a beam with helical phase fronts and orbital angular momentum reveals a subtle connection between macroscopic physical optics and microscopic quantum optics. These amazing properties provide a new understanding of a wide range of optical and physical phenomena

including twisting photons

spin–orbital interactions

Bose–Einstein condensates

etc.

while the associated technologies for manipulating optical vortices have become increasingly tunable and flexible. Hitherto

owing to these salient properties and optical manipulation technologies

tunable vortex beams have engendered tremendous advanced applications such as optical tweezers

high-order quantum entanglement

and nonlinear optics. This article reviews the recent progress in tunable vortex technologies along with their advanced applications.
