I'm sure many readers of Universe Today are, like me, fans of the science fiction genre. From the light sabers of "Star Wars" to the neuralyzer of "Men in Black," science fiction has crazy inventions ...

Researchers at EPFL have developed a chip-scale blue laser that combines stable light emission with rapid frequency control, ...

Researchers have developed an all-light communication network that enables seamless connectivity across space, air and underwater environments. The new network design combines different types of light ...

Visible light communication (VLC) harnesses the visible spectrum, typically emitted by light-emitting diodes or laser diodes, to transmit data in addition to providing illumination. By modulating the ...

Researchers have demonstrated a prototype all-light communication network that can achieve seamless connectivity across air, land and underwater environments, even when communication nodes are on ...

A VLC system consisting of a transmitter and a receiver was constructed, and a serializer/deserializer using 8B13B coding was implemented on an FPGA. The data modulated onto the LED light were ...

As sighted creatures, humans have always used light for communication through body language, writing, smoke signals, and more. Harnessing invisible frequencies of light such as radio massively ...

With the evolution of the sixth-generation (6G) mobile communication toward a space-air-ground-sea integrated network, massive data-centric applications, such as augmented/virtual reality (AR/VR), ...

Warp-drives are solutions of general relativity widely considered unphysical due to high negative energy requirements. Most research has focused on macroscopic solutions towards the goal of ...

Amici direct vision prism. Image by D-Kuru. CC BY-SA 3.0 Scientists have developed a new platform that produces ultrashort UV-C laser pulses and detects them at room temperature using atom-thin ...

In a breakthrough that could help revolutionize wireless communication, researchers unveiled a new method for manipulating terahertz waves, allowing them to curve around obstacles instead of being ...
