Figure 1 |  A single-photon source based on topological bulk cavity with high efficiency. a Schematic of the single-photon source, featuring a single quantum dot (QD) coupled to a ‘Q’-shaped topological bulk cavity. Inset: Unit cells of trivial and non-trivial PCs. b Auto-correlation measurement for QD emitted photons. c Simulated extraction efficiency of the optimized single-photon source as a function of NA. Inset: Angle-resolved far-field |E|2 distribution of the optimized structure.
