HL 13: Focus Session: GaN-based single photon emitters

Tuesday, April 2, 2019, 09:30–12:45, H31

Sources of single photons will be of use for future quantum technologies. Although there are several technologies that can be used for the emission of single photons, in recent years III-nitride based quantum dots (QDs) have been the subject of increased attention due to their possible operation over a wide range of wavelengths from the ultraviolet to the red end of the visible spectrum. Furthermore, III-nitride QD-based single photon sources have also been shown to operate at room temperature and even at elevated temperatures.

Organizers: Frank Bertram, Jürgen Christen (OvGU Magdeburg), and Markus Wagner (TU Berlin)
