Recently, vector beams with special intensity and phase distribution have received much attention due to their unique properties. In this paper, we construct the double‐petal linear edge dislocation (DPLED) beams based on Gaussian vortex beams. The distribution of intensity, polarization, and spin angular momentum (SAM) of the DPLED beams is analyzed in tightly focused based on the Richards‐Wolf vector diffraction theory. The significant difference is occurred in light field, polarization SAM, and polarization distributions before and after focusing of DPLED beams. It's of certain importance for expanding the application of vector beams in optical control, optical imaging, and other fields.

“…Structured light beams [1][2][3][4][5] with phase and polarization singularity are demanded in many applications, including optical trapping and manipulation of micro-and nanoparticles [6][7][8][9][10][11] , optical information transmission [12][13][14][15][16][17][18][19] , laser structuring [20][21][22][23][24][25][26][27][28][29] , and others. Due to their special properties, the greatest attention of researchers is drawn to cylindrically polarized beams [30][31][32][33][34][35] , especially beams with radial and azimuthal polarization.…”

In this paper, it is proposed to use Brewster angle refraction on a conical surface to form an azimuthally polarized beam. After reflection from the conical interface of the two media, the azimuthally polarized beam is conically divergent. An azimuthally polarized beam has a vortical phase dependence. In order to collimate the output beam and make it plane-parallel, it is proposed to use one, two or three conical surfaces combined in one element. The outer surface is used to collimate the converted beam, which significantly distinguishes the proposed element from previously proposed approaches. We have named the refractive optical elements Volcone, Tetracone, and Tricone. The Volcone produces ring shape beam and the Tricone and Tetracone produce round shape beam. The polarization states of the rays when passing through the interface of the media, as well as polarization transformations using the proposed elements using our own developed ray tracing program taking into account polarization, are investigated. The description of the polarization state was carried out using Jones notation. The Volcone is fabricated by diamond turning, in which an internal conical cavity is made. The paper describes a method for calculating the path of beams through refractive conical elements, taking into account phase and polarization conversions. The Volcone is experimentally made of polymethyl methacrylate on a computer numerical control milling machine. The experiment with the Volcone demonstrates the effectiveness of the proposed element. We present Tricone geometry calculation for the following manufacturing.

“…Theory for the transfer of angular momentum (AM) from the incident OV beam to the target has already been developed extensively in terms of theory based on structured beam optics and quantum mechanics. [9][10][11][12][13][14] AM transfer from light to matter can be maximized using LPRs because multipole excitation can be controlled selectively according to the total angular momentum (TAM) of the incident OV, while maintaining the benefits of the general LPR excited by a plane wave beam -such as enhancement and light confinement effect. [4,5,15] Dipole-forbidden or "dark" multipole plasmon modes, such as the quadrupole, typically show lower radiative losses and higher quality factors than dipole modes.…”

“…[18] Indeed, the important role that vortex beams can have in their interaction with plasmonic nanostructures is at the forefront of sensing the chirality of OV in light-matter interactions. [12,14,[19][20][21][22] Therefore, LPR excitation by OV beams has the potential to pave a new path in plasmonics and chiral optics. Previous reports have focused only on 2D structures such as metal nanoplates [4,5,18,23] and nanohole substrates.…”

Plasmonic interactions between an asymmetrically coated ore–shell (ACCS) nanoparticle and an optical vortex produce a novel engagement of the spin angular momentum (SAM) and the orbital angular momentum (OAM) of the input. Simulations based on a discrete dipole approximation (DDA) indicate that the SAM and the OAM of the incident beam determine the modal order of resonance, correctly identifying the peak wavelength, and both the direction and magnitude of optical torque exerted upon the excited, localized plasmon resonance in the ACCS particle. These simulations also indicate higher‐order resonances, including hexapole and octupole modes, and a zero‐order resonance (expressible as a monopole mode), can be excited by judicious selection of the SAM and OAM. A detailed symmetry analysis shows how the multipoles associated with eigenmode excitations connect to the radiation multipoles at the heart of the multipole expansion. It is also shown how additional, distorted resonance modes due to the asymmetricity of the structure are also exhibited. These specific plasmonic characteristics, which cannot be realized by plane wave excitation, become possible through the ACCS asymmetry engaging with the distinct optical vortex nature of the excitation.
