• Sending information on light beams, instead of electrical signals, allows data to be transmitted thousands of times more quickly. But controlling the light beams without losing their energy has been the challenge. Microchip and computer manufacturers however, are increasingly looking to light as the best way to overcome speed bottlenecks associated with today’s electronics.
  • Kuebler and his students used direct laser writing, a kind of nanoscale 3D printing, to create the miniature lattices. The team then ran light beams through the lattices and confirmed that they could flow light without loss through turns that are twice as tight as any done previously.
  • The finding is significant because with the demand for ever-smaller and faster computers and hand-held devices, engineers need ways to pack ultra-fast data-transmission devices into smaller spaces.
