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 are required. To connect these cells will require high-performance transmission lines at high frequencies up to the terahertz range. Moreover, seamless connection to glass fiber networks must be ensured, if possible. 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.
