"Researchers at Aalto University's Department of Applied Physics have found a new way to create tiny hurricanes of light—known to scientists as vortices—that can carry information. The method is based on manipulating metallic nanoparticles that interact with an electric field.
The design method, belonging to a class of geometries known as quasicrystals, was conceived by Doctoral Researcher Kristian Arjas and experimentally realized by Doctoral Researcher Jani Taskinen, both from Professor Päivi Törmä's Quantum Dynamics group. The discovery represents a fundamental step forward in physics and carries the potential for entirely new ways of transmitting information.
The study is published in the journal Nature Communications."
