By forcing light to go through a smaller gap than ever before, researchers have paved the way for computers based on light instead of electronics.
Researchers at Eindhoven University of Technology have come up with a surprising solution: a wireless network based on harmless infrared rays. The capacity is huge - more than 40Gbit/s per ray.
As optical computing becomes a more realistic prospect, lasers will be required to connect components inside our devices. Now, a new silicon-based laser could make it far easier for researchers to replace wires with beams of light.
