Vortex Lenses - Spiral Phase Plates

The vortex lens, which is also known as a spiral phase plate or a vortex phase plate, transforms an incident Gaussian laser beam profile to a doughnut shaped beam profile or so colled optical vortex. Most important properties of a vortex lens are: accordance to the wavelength, topological charge and amout of steps. Our vortex lenses show a very small deviation from the theoretical height (usually ± 5nm), which leads to a high correspondence with the applicable laser wavelength. The topological charge effects the orbital momentum of the resulting doughnut beam. We cover topological charges in a range of 1 to 32 (higher topological charches are also possible). A higher amount of steps of a vortex lens result in a darker center region of the doughnut beam, this parameter is crucial for several applications of the vortex lens, such as STED, MINFLUX, atomic and molecular excitation, optical vortex coronagraphs, nano-lithography, laser cutting and machinery, data transfer and optical twezzers manipulations. Our vortex lenses posess 64 steps and we plan to build stepless spiral phase paltes in near future.

What are the spiral phase plates?

Our spiral phase plates (SPPs) also known as vortex lenses or vortex phase plates are advanced optical elements used to manipulate light in a unique and precise manner, transforming the phase structure of light waves as they pass through. These innovative devices have revolutionized various fields, including microscopy, optical communication, and quantum computing, by enabling the control and generation of optical vortices and beams with orbital angular momentum.

Spiral phase plates are designed to impart a helical phase shift to the light waves that travel through them. This special attribute allows SPPs to convert a standard light beam into an optical vortex, characterized by a spiral wavefront and a phase singularity at its core. The ability to generate and manipulate these vortices opens up a plethora of applications in optical manipulation, data transmission, and even in the study of quantum properties of light.

Schematic surface geometry of a spiral phase plate

The working principle of spiral phase plates centers on their unique geometric structure. Made from optical grade fused silica, our phase plates are engineered with a spiral staircase-like surface, where the thickness of the plate increases in a helical manner from the center to the outer edge. As light passes through the varying thickness of the plate, it experiences different optical path lengths, resulting in a phase shift that increases with the angular position. This phase modulation introduces a twist into the wavefront of the light, creating an optical vortex with a phase singularity at its axis.

Our spiral phase plates could be applied in numerous technological and scientific fields. In optical tweezers, they enable the trapping and manipulation of particles with high precision. In optical communications, SPPs enhance data capacity by encoding information in the light's orbital angular momentum, offering a novel solution to bandwidth limitations. Furthermore, in microscopy and imaging, these devices improve resolution and contrast by exploiting the unique properties of optical vortices.

How does the resulting beam looks like?

The following plot displays a 3x3 grid of Laguerre-Gaussian modes, each labeled with its corresponding azimuthal index l in the top right corner. Each subplot illustrates the intensity distribution of the mode. The grid is plotted on axes in millimeters, showing how the modes vary in structure as the topological charge l increases. The modes are calculated using a fixed radial index p=0 and varying l values, showcasing distinct doughnut shapes for higher l.

The second plot illustrates the relationship between the topological charge l and the normalized doughnut diameter. The diameters are scaled so that the mode with l=1 has a diameter of 1 mm. This plot highlights how the doughnut diameter increases with the topological charge, offering insight into the geometric properties of Laguerre-Gaussian modes as l varies.

The following image grid shows the intensity patterns of a Gaussian beam modified by Spiral Phase Plates with topological charges ranging from l=0.90 to l=1.10. Each intensity distribution displays a doughnut-shaped ring structure, characteristic of optical vortices, with varying diameters and sharpness depending on the topological charge. The use of zero-padding and a Gaussian filter effectively reduces numerical artifacts, enhancing the visual clarity and symmetry of the beam’s intensity patterns. The variation is relative to the central wavelength, for example l = 1.01 means that the Spiral Phase Plate is shifted by +1% to the laser beam (laser = 526,68nm, SPP = 532nm).

Application notes

1) Removing the cleaing / protective polymer

To ensure the protection and cleanliness of our products during shipping, we utilize a specialized optical grade polymer. Before using the optical elements in your setup, please remove the polymer from the surface using the provided sticker. For a detailed explanation, refer to this video by the polymer manufacturer:

2) Preparing the laser beam

The quality of the original laser beam is crucial for the resulting beam after passing through the phase plate. To ensure optimal quality, please employ spatial filtering for the original beam. In certain scenarios, a siplified variation of spatial filtering can be implemented:

how to improve the quality of the original laser beam

Spatial filtering is achieved by focusing the laser beam through a lens onto a pinhole, effectively removing spatial distortions and noise. Only the central, most coherent part of the beam passes through the pinhole, thereby improving its quality. A second lens is then used to recollimate the beam to the desired diameter, and an additional iris can be employed to remove remaining higher-order diffractions.
