Eine neue Art der Lichtsteuerung könnte die drahtlose Technologie der Zukunft voranbringen

„A new device lets scientists switch ultra-stable, donut-shaped light patterns that could carry future wireless data.

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called skyrmions. These light vortices hold their shape even when disturbed, making them promising for wireless data transmission. Using a specially designed metasurface and controlled laser pulses, scientists can flip between electric and magnetic modes. The advance could help pave the way for more resilient terahertz communication systems.“
