Optical knots and links have attracted great attention because of their exotic topological characteristics. Recent investigations have shown that the information encoding based on optical knots could possess robust features against external perturbations. However, as a superior coding scheme, it is also necessary to achieve a high capacity, which is hard to be fulfilled by existing knot-carriers owing to the limit number of associated topological invariants. Thus, how to realize the knot-based…

Optical framed knots as information carriers
TLDR
This work introduces the experimental realization of structures known as framed knots within optical polarization fields and develops a protocol in which the topological properties of framed knots are used in conjunction with prime factorization to encode information.
Tying Polarization‐Switchable Optical Vortex Knots and Links via Holographic All‐Dielectric Metasurfaces
Tailoring the spatial structure of light field in multiple degrees of freedom is a research hotspot in recent years. The topology of light field, as one of the most fascinating structures, such as
Knotting of optical vortices
Optical vortices form three-dimensional lines of darkness in scalar light. They are places where the phase becomes undefined and hence singular in value. We study the ability of optical vortices to
Creation of acoustic vortex knots
TLDR
It is found that the knot function can be embedded into the acoustic field by designed metamaterials with only 24 × 24 pixels, and the acoustic fields with Hopf link and trefoil knot vortex lines have been observed experimentally.
Ultrasmall Optical Vortex Knots Generated by Spin‐Selective Metasurface Holograms
Tying isolated vortex knots in complex optical fields has been recently realized using spatial light modulators (SLMs). These traditional devices suffer from low efficiency, narrow bandwidth, and
Topological photonics
Topological photonics is a rapidly emerging field of research in which geometrical and topological ideas are exploited to design and control the behavior of light. Drawing inspiration from the
Topological mechanics of knots and tangles
TLDR
The authors show why some common knots slip easily and untie, whereas others hold tight, and highlight the importance of twist and writhe in unknotting processes, providing guidance for the control of systems with complex entanglements.
Reconfigurable Knots and Links in Chiral Nematic Colloids
TLDR
The knotting of microscopic topological defect lines in chiral nematic liquid-crystal colloids are demonstrated by using laser tweezers as a micromanipulation tool, demonstrating how relevant the topology can be for the material engineering of soft matter.
Knotting fractional-order knots with the polarization state of light
The fundamental polarization singularities of monochromatic light are normally associated with invariance under coordinated rotations: symmetry operations that rotate the spatial dependence of an
Stable knot-like structures in classical field theory
In 1867, Lord Kelvin proposed that atoms—then considered to be elementary particles—could be described as knotted vortex tubes in either1. For almost two decades, this idea motivated an extensive
