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 graphene-based material converts incoming terahertz pulses (from above) into visible light in an ultrafast and controllable manner - optimal for data transport in optical fibers. (Image: B. Schröder ...

Photo of a supercontinuum being generated by a short-pulsed laser. The creation of a plasma produces light that spans the visible and invisible parts of the electromagnetic spectrum. The search for ...

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 ...

Terahertz (THz) waves, which are located between microwaves and infrared light in the electromagnetic spectrum, can pass through many materials without causing damage, making them useful for security ...
