You are watching a long-standing assumption in physics and engineering quietly fall apart. Researchers at Northwestern ...

The bottom of the sea is a mysterious and inaccessible place, and anything unfortunate enough to slip beneath the waves and into the briny depths might as well be on the Moon. But the bottom of the ...

The World Wide Web might sound metaphorical, but it’s actually grounded in a physical web of translucent glass filaments crisscrossing the globe. These fiber-optic cables transmit internet data ...

A new type of optical fiber filled with nothing but thin air has been found to be particularly effective for carrying out quantum key distribution (QKD), a security protocol that is in principle ...

Tubular laser beams can create what amount to fiber-optic cables made of thin air, researchers report in a study to appear in Physical Review X. Laser-heated air can efficiently transmit light signals ...

Fiber-optic services are becoming more popular, and networks are expanding to cover more areas for faster data transfer speeds. Fiber-optic data transfer differs from traditional methods like ...

In Sept, 2025, Microsoft Azure announced it is scaling its hollow core fiber (HCF) production by outsourcing manufacturing to ...

Since the first fiber optic cables rolled out in the 1970s, they've become a major part of everything from medical devices to high-speed internet and cable TV. But as it turns out, one group of marine ...
