Researchers of the Fraunhofer Institute for Applied Solid State Physics and the Karlsruhe Institute for Technology have achieved the wireless transmission of 40 Gbit/s at 240 GHz over a distance of one kilometer. Their most recent demonstration sets a new world record and ties in seamlessly with the capacity of optical fiber transmission. In the future, such radio links will be able to close gaps in providing broadband internet by supplementing the network in rural areas and places which are difficult to access.

Due to its physical properties diamond is a promising material for optomechanical applications. For the first time, researchers have managed to use polycristalline diamond to manufacture an optical circuit. The results impress with very high optical quality, as the relevant article in Nature Communications shows (DOI: 10.1038/ncomms2710).

UV lamps are used to cure coatings and adhesives in many industrial manufacturing processes. And special sensors are used to measure the intensity of the UV light applied to these surfaces. But because these sensors age too quickly, they can only be used to record intermittent measurements. Fraunhofer researchers have developed a new generation of sensors capable of continuously monitoring UV intensity. These devices will be presented for the fi rst time at the Sensor + Test trade show in Nuremberg, from May 14 to 16 (Hall 12, Booth 537).

When satellite Proba-V flies into space in the coming weeks in order to begin its earth observation, the first European device based on the semiconductor gallium nitride will be on board. Being more robust, more compact and lighter than traditional solutions, the new technology promises to significantly improve communication electronics in space. In the course of an intensive test series, the amplifier developed by the Fraunhofer Institute for Applied Solid State Physics IAF in Freiburg has qualified itself for the journey into space.
