Abstract: The present invention relates to a single photon source, comprising: a microcavity arranged between a concave first minor and a semiconductor heterostructure forming a planar second minor, wherein the microcavity supports an optical mode, a quantum dot embedded in the semiconductor heterostructure and facing the first minor, and a laser light source configured to provide laser light in the microcavity to excite the quantum dot to emit single photons exiting the microcavity.
