Light can tie knots—literally. Engineers at Duke University have managed to manipulate laser beams to form intricate 3D patterns called optical knots, using custom-designed optics. These twisted beams ...

Knots are generally understood to form due to twists and turns of long, flexible materials that keep shoes on your feet or ...

Engineers at Duke University have successfully manipulated laser beams to create intricate 3D patterns known as 'optical ...

able to restore chaotic signals in free-space optical communication links distorted by atmospheric turbulence. Using a system of optical antennas integrated into a programmable photonic chip, the ...

The black, rectangular box where turbulence was created for laser light to pass through. The setup allowed researchers to demonstrate the stability of optical knots as they pass through turbulence.

NEC has successfully achieved Japan's longest terrestrial wireless optical communication, or free-space optical (FSO) ...

In a large variety of fields, the development of ever more demanding optical systems now requires a thorough understanding of the impact of atmospheric turbulence together with the development of ...

Adaptive Optics Market. The global adaptive optics market is poised for significant growth, with demand expected to rise at ...

The work shows that optical knots could be used as a reliable method to transmit encoded information or to measure turbulence in pockets of air. Knots are generally understood to form due to ...
