Researchers have, for the first time, used a semiconductor laser to send and receive radio signals. The hybrid electronic-photonic device uses a laser to extract and transmit microwave signals ...

The laser communications transmitter for the Psyche spacecraft is a key component of the Deep Space Optical Communications (DSOC) package that is designed to transmit data in photon packets from ...

ORLANDO, Fla., June 9 (UPI) --New space missions being launched this summer will attempt to revolutionize space communications by using laser beams to quickly transmit large amounts of data ...

Tuning in: interfering laser light could soon be used to generate terahertz signals. (Courtesy: iStock/arttanja) A new type of microwave radio transmitter built by physicists in the US could lead to ...

Using a single laser and a single optical chip, researchers were able to transmit 1.8 petabits per second.

The goal is to transmit at least 1,000 watts of power over a distance of a kilometer (0.6 mile) or more.

The transmitter features wavelength tunability of up to 20 channels spaced at 50-GHz intervals. Based on electroabsorptive modulated laser (EML) technology, the transmitter combines a tunable laser ...
