Replacing electricity with light: First physical ‘metatronic’ circuit created.

The technological world of the 21st century owes a tremendous amount to advances in electrical engineering, specifically, the ability to finely control the flow of electrical charges using increasingly small and complicated circuits. And while those electrical advances continue to race ahead, researchers at the University of Pennsylvania are pushing circuitry forward in a different way, by replacing electricity with light.

  1. So, when we finally get a diode that rectifies light, we’ll finally have the most efficient solar power recovery method yet to date.
