Future wireless data networks will have to reach higher transmission rates and shorter delays, while supplying an increasing number of end devices.

For this purpose, network structures consisting of many small radio cells will be required.

Researchers of Karlsruhe Institute of Technology (KIT) use ultra-rapid electro-optical modulators to convert terahertz data signals into optical signals.

This is reported in Nature Photonics (DOI: 10.1038/s41566-019-0475-6).

While the new 5G cellular network technology is still tested, researchers are already working on technologies for the next generation of wireless data transmission.

between microwaves and infrared radiation in the electromagnetic spectrum.
