In 1954, three scientists observed a paradox to which they gave their name: the Fermi-Pasta-Ulam recurrence. Now, fibre optics are on the way to finally providing an explanation.
To understand what is happening in an optical fibre, physicists can mimic a rupture of the flow of grains of light – the photons – thanks to a laser device.
World-class fiber-based internet service is available in less than a quarter of Los Angeles County. By contrast, it’s almost ubiquitous in Stockholm and Paris.
The design of a new chip to detect the twisted nature of light waves could pave the way for next generation of optical communication technologies.
Whatever BT, Virgin Media and other telecoms firms may say, the only future-proof network is a fibre-optic from door-to-door.
The cloud lies under the ocean. Thin cables about as big around as a garden hose traverse the Earth’s oceans carrying all our intercontinental internet data.
