Propagating dimensions of light: Deforming versatile non-diffractive beams along the optical trajectory

https://phys.org/news/2024-04-propagating-dimensions-deforming-versatile-diffractive.html

"on-chip non-diffracting light fields: higher resolution, less difficulty encoding phase profile... metasurfaces using nanoscale antenna miniaturizing optical... reconstructed non-diffracting light field along propagation path, circularly Airy beams into non-diffracting bullet beam after propagating a distance... joint local-global phase control of radial phase gradient and encoding more complex, non-diffracting optical fields... triple birefringent nanoantennas doubled light field types to 6... high tolerance to manufacturing defects"
