We report on a quantum dot micropillar-based single-photon source demonstrating tunable emission energy via an applied electric field and driven by an on-chip, whispering-gallery-mode microlaser. In this concept the cavity-enhanced single-photon source is monolithically integrated with an electrically driven, coherent excitation source. The device concept features low laser-threshold currents of a few tens of μA, has a small footprint of ∼200 μm2 and demonstrates high single-photon purity with… CONTINUE READING
