This work demonstrates a high-brightness quantum dot single-photon source integrated into a GaAs-on-insulator microring resonator. The authors performed finite element simulations using JCMsuite to calculate the theoretical quality factor of the microring cavity, which was a key parameter for estimating the Purcell enhancement and coupling efficiency of the quantum dot to the resonator modes. These simulations were essential for designing the photonic structure to optimize light-matter interaction.
