Microresonator-enhanced quantum dot single-photon emission in GaAs-on-insulator platform
Résumé
Abstract Single-photon emitters play a crucial role in integrated photonic quantum systems across various material platforms. In this study, we present a cavity-enhanced quantum dot single-photon source in a high-index contrast material platform (GaAs-on-insulator). A quantum dot is embedded in a microring resonator with a quality factor of approximately 9000, where the cavity-induced light enhancement results in a spontaneous emission acceleration factor of around 2.6, and we achieve a g(2)(0) as low as 0.03±0.02 and post-selected two-photon interference visibility of 51.7% ± 3.2% for the single-photon source. This demonstration shows the potential of the GaAs-on-insulator platform for scalable on-chip quantum information processing
