As part of a project funded under the Collaborative Research Centre / TRR 142, Paderborn researchers from the Department of Physics and the Institute for Photonic Quantum Systems (PhoQS) have succeeded in manufacturing quantum dots – nanoscopic structures where the material’s quantum properties come into play – that glow in the optical C-band at wavelengths of 1530 to 1565 nanometres.
