Shifting Modes Enable Free-Space Optical Communication
VIENNA, Nov. 12, 2014 — Twisted beams of light have been used to transmit images through the air over 3 km, demonstrating significant data-carrying capacity of light in free-space communications. A team from the Institute for Quantum Optics and Quantum Information (IQOQI), in collaboration with the University of Vienna, performed this feat by adjusting the spatial modulation of a green laser beam. Sixteen laser modes were used to encode real information, including grayscale images of Wolfgang Amadeus Mozart,...
