Light consists of a flow of photons. If two waveguides – cables for light – lie side by side, they attract or repel each other. The interaction is due to the optical force, but the effect is usually extremely small. Physicists at Chalmers University of Technology and Free University of Brussels have now found a method to significantly enhance the optical force. The method opens new possibilities within sensor technology and nanoscience. The results were recently published in the prestigious scientific journal Physical Review Letters.
