Experimental study demonstrates single-photon emission in tungsten disulfide micro-domes coupled to an optical cavity, highlighting tunable platforms for quantum technologies.
Versatile, tunable, and potentially scalable single‐photon sources are a key asset in emergent photonic quantum technologies. In this work, a single‐photon source based on WS 2 micro‐domes, created via hydrogen ion irradiation, is realized and integrated into an open, tunable optical microcavity. Single‐photon emission from the coupled emitter–cavity system is verified via the second‐order correlation measurement, revealing a value of . A detailed analysis of the spectrally selective, cavity enhanced emission features shows the impact of a pronounced acoustic phonon emission sideband, which contributes specifically to the non‐resonant emitter–cavity coupling in this system. The achieved level of cavity–emitter control highlights the potential of open‐cavity systems to tailor the emission properties of atomically thin quantum emitters, advancing their suitability for real‐world quantum technology applications.
