Scientists have turned a long-standing sci‑fi idea into working hardware, using pure light to move data wirelessly through the air instead of relying on radio waves or copper traces. The result is a ...

The recent development in the utilization of flexible optical fiber sensors and the prospective application scenarios were then summarized, which encompass human activity monitoring and healthcare, ...

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 ...

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 ...

Commercialization has started for network switches based on co-packaged optics (CPO), which are capable of routing signals at terabits per second speeds, but manufacturing challenges remain regarding ...

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water. Researchers have developed a new optical sensor ...

Carbon nanotubes are moving from lab curiosities to workhorse components in quantum hardware, and one of the most striking examples is their use as single-photon light sources. By exploiting their ...
