Singularities in cylindrical vector beams [PDF]

open access: yesJournal of Modern Optics, 2015
Cylindrical vector beams with azimuthal and radial polarization distributions are studied for singularities. It is shown experimentally that these beams have screw dislocation as well as edge dislocation at the same time. The relation between phase and polarization of light beam is the key to understand this fact.

Optical trapping and optical binding using cylindrical vector beams [PDF]

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2011
We report on the use of cylindrical vector beams for optical manipulation of micron and sub-micron sized particles using the methods of a single-beam gradient force trap (optical tweezers) and an evanescent-field surface trap (optical binding).

On-chip generation of adjustable cylindrical vector beams [PDF]

open access: yesOptics Express, 2023
Cylindrical vector (CV) beams have sparked considerable interest due to their extraordinary vectorial properties, desirable for applications ranging from microscopy to high energy physics. Increasing demand for cost-effective, small-footprint photonics has fueled the development of photonic integrated circuits (PICs) capable of generating structured ...

Sagnac Interferometer Based Generation of Controllable Cylindrical Vector Beams [PDF]

open access: yesInternational Journal of Optics, 2016
We report on a novel experimental geometry to generate cylindrical vector beams in a very robust manner. Continuous control of beams’ properties is obtained using an optically addressable spatial light modulator incorporated into a Sagnac interferometer.

Structured beam-driven multipolar mode control in nanoparticles [PDF]

open access: yesNanophotonics
Due to their unique tight focusing properties, structured light beams, such as cylindrical vector beams, offer unique opportunities for tailoring light–matter interaction at the nanoscale.

Focusing of high numerical aperture cylindrical-vector beams

open access: yesOptics Express, 2000
Cylindrical-vector beams are of increasing recent interest for their role in novel laser resonators and their applications to electron acceleration and scanning microscopy. In this paper, we calculate cylindrical-vector fields, near the focal region of an aplanatic lens, and briefly discuss some applications.

Monolayer Chiral Metasurface for Generation of Arbitrary Cylindrical Vector Beams

open access: yesPhotonics
The cylindrical vector beam (CVB) has been widely studied and applied in recent years. However, many CVB generation methods suffer from complex systems, and large-size devices are required. Here, we propose a monolayer chiral metasurface composed of spin-

Dynamic control of cylindrical vector beams via anisotropy

open access: yesOptics Express, 2018
We demonstrate that the spatially diffractive properties of cylindrical vector beams could be controlled via linear interactions with anisotropic crystals. It is the first time to show experimentally that the diffraction of the vector beams can be either suppressed or enhanced significantly during propagation, depending on the sign of anisotropy ...
