Free-space light could power high-speed optical WiFi
Plasmonic speed enhancements previously constrained to nanoscale phenomena are replicated on macroscopic optical devices.

"In this demonstration, our structure acts to efficiently relay the photons from a wide angle into a narrow angle without losing speed," said Mikkelsen. "We didn't integrate a regular fast photodetector like the Connectivity Lab did in their original paper yet. But we solved the major bottleneck in the design and the future applications are very exciting!”
