The data repository can create the figures of the publication Jurkat et al. Single-Photon Source in a Topological Cavity. Nano Lett. 23, 820–826 (2023). All relevant information on the science can be found in the publication. In the publication we investigate the coupling of a single optically active semiconductor quantum dot to the zero-dimensional topological protected defect at the end of a Su-Shrieefer-Heeger chain, which is composed of a zig-zag chain of coupled microresonators. For more details, please refer to the original publication.
