Abstract
We present the experimental generation and analysis of both the intensity and phase of an optical vortex beam originating from a superposition of Airy-vortex beams. A new theoretical proposal is accessible to generate an array of Airy-vortex beams (AiVBs) from a superposition of N identical AiBs symmetrically located with respect to the propagation axis, where each beam is superimposed with OV and are characterized by the same topological charge l. Additionally, a single experimental apparatus enables both the optical generation and reconstruction of computer-generated holograms implemented on a spatial light modulator and its phase analysis by digital holography. The experimental results agreed with the theoretical predictions. The array of Airy-vortex beams has potential applications for trapping and rotating micro-particles in optical tweezers, modulation in optics communications, optical metrology, and others in optics and photonics.
