Researchers Create Single-Photon Emitters at Desired Positions

Researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), TU Dresden, and Leibniz-Institut für Kristallzüchtung (IKZ) have demonstrated the controlled creation of single-photon emitters in silicon at the nanoscale. According to the researchers, the technology, which is compatible with current CMOS fabrication methods, represents a promising candidate for photonic quantum technologies, with a fabrication pathway that is compatible with very large-scale integration. Previous quantum photonics experiments required the use of “bulk optics.” These space-consuming elements would be distributed across the optical table and could occupy vast amounts of laboratory space. Now, photonic chips are changing this...
