A study demonstrates that graphene-based materials can be used to efficiently convert high-frequency signals into visible light, and that this mechanism is ultrafast and tunable. These outcomes open ...

A study carried out by a research team from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), the Catalan Institute of Nanoscience and Nanotechnology (ICN2), University of Exeter Centre for Graphene ...

How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

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 ...

Have you ever wondered what the invisible world of radio waves might look like if you could actually see it? Rootkid explains how his project, the Spectrum Slit, transforms the unseen chaos of ...

A high-brightness ultrabroadband supercontinuum white laser has attracted more and more attention in physics, chemistry, biology, materials science, and other disciplines of science and technology.

SMART Hub’s proposed way out is sharing. A radar operating near 3.1 gigahertz could sense a nearby wireless network, shift to ...
