Focusing a cylindrical vector beam and the Hall effect

Компьютерная оптика
Polarization of a higher-order cylindrical vector beam (CVB) is known to be locally linear. The higher the beam order, the larger number of full circles the local linear polarization vector makes around the optical axis.

Nonparaxial Exploding Cylindrical Vector Beams

Photonics
Exploding or concentrating beams, vortex beams, and cylindrical vector beams have a precisely shaped transversal amplitude profile such that they produce a continuously concentrating and intensifying focal spot upon focusing as the lens aperture is ...

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

Atti 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).

Monolayer Chiral Metasurface for Generation of Arbitrary Cylindrical Vector Beams

Photonics
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-

Bamboo-Slip-Inspired Conformal Reconfigurable Metasurfaces. [PDF]

Adv Sci (Weinh)
Bamboo‐slip‐inspired conformal reconfigurable metasurface system. The structure is mainly composed of three parts, which are conformal metasurface, pattern reconfigurable antenna, and control components (such as Field Programmable Gate Array (FPGA)). Conformal metasurfaces draw inspiration from the design of ancient Chinese bamboo slips.

An interference scheme for generating inhomogeneously polarized laser radiation using a spatial light modulator [PDF]

Компьютерная оптика, 2020
An optical system for converting linearly polarized laser beams into cylindrical vector beams is developed and experimentally investigated. The scheme is based on the coherent addition of mode beams using a Mach-Zehnder interferometer. The simplicity and

An all-fiber Raman laser for cylindrical vector beam generation

, 2022
Art. 125108, 8 S.We demonstrate a compact Raman all-fiber oscillator for cylindrical vector beam generation. The laser is based on a strongly guiding passive fiber with two fiber Bragg gratings inscribed in it, which separates the different transverse ...

A miniaturized acoustic vector sensor with PIN-PMN-PT single crystal cantilever beam accelerometers

Acta Acustica, 2020
Directional sound detection using vector sensors rather than large hydrophone arrays is highly advantageous for target detection in SONAR. However, developing highly sensitive and compact vector sensors for use in a system whose size is limited has been ...
