Organic molecule photon number adjustable quantum emitters — •Yijun Wang, Subhabrata Ghosh, Maximilian Luka, and Ilja Gerhardt — Institut für Festkörperphysik, Leibniz Universität Hannover, Appelstraße 2, D-30167 Hannover, Germany
We utilize single molecule microscopy under cryogenic conditions to implement non-classical photon sources. Our near-sodium-resonant photon emitters are based on organic molecules, and allow for triggered photon emission with a narrow bandwidth and an adjustable photon number per trigger. We implement off-resonant excitation on DBATT molecules and detect the near-sodium resonant photons behind an atomic vapor filter based on the Faraday effect. The photons are generated in a “press-button” style. The single photon purity is well justified by the low value of g(2)(0). Alternatively, we can adjust the photon number per trigger by the DC Stark shift.
