Researchers have achieved data rates as high as 424Gbit/s across a 53-km turbulent free-space optical link using plasmonic modulators—devices that use special light waves called surface plasmon polaritons to control and change optical signals. The new research lays the groundwork for high-speed optical communication links that transmit data over open air or space.
And the UK have tested their laser weapons this year and took out a drone with them last month.
Who would’ve guessed that light goes at the speed of light
Btw, weren’t there some mach-10 railguns against hypersonic missiles around? Or was that a hoax?
