Paper Abstract

The quest for efficient light sources and light detectors is a driving force in the development of semiconductor quantum dot (QD) devices. Self assembled QDs in bulk material are characterized by high quantum efficiency and can act as single photon emitters. However, they suffer from a poor light in- and outcoupling efficiency. We demonstrate highly efficient QD-micropillar based light detectors and single photon emitters exploiting cavity quantum electrodynamics (cQED) effects. An advanced fabrication technique allows us to realize ultra sensitive and wavelength selective light detectors as well as triggered, electrically driven single photon sources with photon outcoupling efficiencies exceeding 60 %.
