“…6, the intensity distributions of a DNB with n = 42 and varying m as well as of a (modulated) Bessel beam of order m are depicted. It was already shown that DNBs can be implemented by interfering nondiffracting Bessel beams [35], which indicates that nondiffracting beam families are transformable among each other. The described behavior of DNBs implies that also Bessel beams can be developed in the frame of DNBs.…”

We investigate discrete nondiffracting beams (DNBs) being the foundation of periodic and quasiperiodic intensity distributions. Besides the number of interfering plane waves, the phase relation among these waves is decisive to form a particular intensity lattice. In this manner, we systematize different classes of DNBs and present similarities as well as differences. As one prominent instance, we introduce the class of sixfold nondiffracting beams, offering four entirely different transverse intensity distributions: in detail, the hexagonal, kagome, and honeycomb pattern, as well as a hexagonal vortex beam. We further extend our considerations to quasiperiodic structures and show the changeover to Bessel beams. In addition, we introduce a highly flexible implementation of the experimental analog of DNBs, namely discrete pseudo-nondiffracting beams, and present locally resolved intensity and phase measurements, which underline the nondiffracting character of the generated wave fields.

“…The OVs are generated in a variety of methods. Synthetic holograms [23,24], laser mode separation [25,26], computer-generated holograms [27], phase masking [28], hologram superimposing Bessel beams [29], holographic meta surface liquid-crystal spatial light modulator (LC-SLM) [30], phase-only SLM [31,32], multiple plane wave interference [33], and deformable mirrors [9]. LC-SLM methods have shown to generate perfect OV [30,34] and gradient-rotation split-ring antenna metasurfaces have shown to generate high purity OVs [35], while the use of spiral phase plates is one of the most often used passive methods for the generation of OVs [36][37][38].…”

Optical vortices have been extensively explored, due to its widespread applications, spanning from optical trapping to laser processing. Previously, several ways for generating optical vortices had been reported. However, none of the previously reported methods demonstrated the design of a geometrically variable tunable spiral plate capable of tuning the optical vortex's features. In this study, we present a three-dimensional tunable spiral plate capable of generating desired vortex and focal characteristics. These spiral plates are 10 µm in width and 7-17 µm in height, generating few µm high vortices. We used the 3D FDTD approach to model and simulate these spiral plates for incident plane waves with a wavelength of 632 nm. We show that the vortex profiles can be tweaked in two ways: by changing the spiral plate's geometrical features along the vertical axis, and by changing its refractive index.

“…The unique optical properties of the optical vortices have been widely used in applications such as optical tweezers [5][6][7][8], image processing [9][10][11], communication systems in free space [12][13][14], and optical fibers [15,16]. Motivated by these applications several methods for generating the optical vortex beam have been proposed [17][18][19][20][21][22][23][24][25][26][27]; however the diameter of these optical vortices is related to their topological charges. This property causes difficulties to achieve a high spatial accuracy and high orbital angular momentum coupling optical vortices into a fiber.…”

We have experimentally created perfect optical vortices by the Fourier transformation of holographic masks with combination of axicons and spiral functions, which are displayed on a transmission liquid crystal spatial light modulator. We showed theoretically that the size of the annular vortex in the Fourier plane is independent of the spiral phase topological charge but it is dependent on the axicon. We also studied numerically and experimentally the free space diffraction of a perfect optical vortex after the Fourier back plane and we found that the size of the intensity pattern of a perfect optical vortex depends on the topological charge and the propagation distance.
