Abstract

We present a disseminable single-photon source based on an InGaAs quantum dot in a micro-mesa. This source achieves a maximum photon flux of 2.8 million photons/s at a wavelength of 929.7 nm, with a multi-photon suppression of g(2)(0) = 0.22. The semiconductor chip can be installed in any cryogenic system and the compact size of all the optical components facilitates easy dissemination for interlaboratory comparisons. The consistency in results regarding photon flux and multi-photon suppression across two distinct laboratory environments underscores the robustness and versatility of this single-photon source.
