At this place it happensElectrons meet photons

Located in the Centre for Semiconductor Technology and Optoelectronics, the chair has had a first-class technical infrastructure since 1998. Together with the Semiconductor Technology Department, the staff use a clean room laboratory with more than 470 square metres of space. In addition to numerous European projects, the Chair of Optoelectronics is also involved in the Centre for Nanointegration CENIDE and the NanoEnergyTechnologyCentre NETZ.

Photonic-excited Integrated THz Beam Steering Antennas

Hetero-integrated InP-based THz antenna array chips have been fabricated and successfully deployed for THz image scanners and mobile THz communications. The video shows wireless communication for the generation after 5G with data rates of over 20 Gbit/s at 300 GHz carrier frequency and beam steering angles of about 45°.

Photonic sensor for skin cancer detection

Millimetre waves (mm-waves) in the range of 30-300 GHz have shorter wavelengths compared to microwaves and therefore only penetrate a few millimetres into the human body. This enables them to detect pathological changes in the skin layers, which are the starting point of most skin tumours. Other biomedical applications of mm-waves include detecting non-invasive dental caries, monitoring blood glucose, assessing corneal hydration, monitoring wound healing and observing human vital signs. Although these concepts are promising, there are significant challenges to overcome to ensure reliable and stable monitoring using mm-waves. This includes the development of a high-precision instrument for skin monitoring.

Faster radio data transmission with RAPID

At the beginning of the year, the European Union, together with Japan, had published a call for collaborative research projects in four specially selected technology areas. Within each of the four focal areas, only one project was to be funded. In the area of "Access Networks for Densely Located User Areas", Duisburg University and its international partners were able to prevail over many other consortia.
