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 ...

It’s a rare person who can pick up a cheap laser pointer and not wield it like a lightsaber or a phaser, complete with sound effects. There’s just something about the “pew-pew” factor that makes ...

A large group of fiber optic lasers are powered by DC current. Laser drive is supplied by a current source with modulation added further along the signal path. The current source, although ...

Tear fluid is emerging as an attractive source of diagnostic information because it can be collected easily and noninvasively ...

A team of researchers from the Accelerator Technology & Applied Physics (ATAP) Division at Berkeley Lab, California, has developed a new technique for combining fiber lasers operating at different ...

A newly developed fiber-optic microphone demonstrates how light-based sensing can overcome the limitations of conventional electronics in extreme environments.

As quantum computers continue to advance, many of today's encryption systems face the risk of becoming obsolete. A powerful ...

Researchers have fabricated a hair-thin microphone made entirely of silica fiber that can detect a large range of ultrasound ...

Telecommunications as an industry is often bogged down by technological inertia. Various regulations and dependencies mean that new innovations often don’t come to market for close to a decade, and ...
