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 cable was once reserved for high-performance needs, but today it’s turning up in all kinds of networks. If you’re familiar with copper cable, you’ll quickly discover that fiber optic cable ...

Fiber-optic sensors work well in tight spots and in applications with a high degree of electrical noise, but care must be taken when specifying these critical components. Sensing part presence in ...
