750,000 euros in funding from the European Regional Development Fund (ERDF) will flow into semiconductor technology at TU Braunschweig until March 2023. Eight funded devices will thus form the MicroPhotonicsLab (MPL) in the nanometrology research centre LENA. The new laboratory structure will make it possible to combine various semiconductor components such as waveguides and laser diodes on one chip. This will allow different photonics research groups to literally merge their expertise on a few millimetres. Bringing together microscopic light emitters with tiny waveguides opens up new possibilities for QuantumFrontier's Topical Group "Structured Illumination at the Nanoscale".
