In this paper, we will deal with the IPM vortex of tightly focused (or nonparaxial) beams that can be applied to practical optical trapping and manipulation experiments. In addition, we now establish ...

This family of beams — also known as vortex beams with a characteristic ... invasive endoscopic probes, optical coherence tomography, fiber-based optical trapping and manipulation of microscopic ...

Compared with mechanical tweezers, optical tweezers use non-contact operation, and has the characteristics of small damage to life and high repeatability. Gahagan et al. [144] used vortex beams to ...

trap arrays or special mode optical trap arrays including optical vortex (OV) arrays, perfect vortex (PV) arrays, and Airy beam arrays, etc., can be generated by addressing various phase holograms.

Abstract: Optical vortex is of great value in optical trapping, manipulating, and arranging. Here, we propose a dual-helical dielectric cone to generate a dual-vortex beam which can be used to ...

In particular, the main advantage of acoustic trapping over optical trapping, namely the ability of sound ... We show that the region of vanishing pressure of a propagating vortex beam can confine a ...

(Nanowerk News) An optical vortex is identified as a phase singularity encircled ... At the same year, this "perfect" vortex beam was demonstrated for dynamical trapping micro-particles along those ...

The transversely misaligned dual-beam optical trap inherently creates an optical force field with a vortex distribution exerted on the trapped particle, which actuates the orbital rotation of the ...
