This work investigates the design, fabrication, and optical characterization of nanobeam cavities on a GaAs-on-insulator platform with integrated InAs quantum dots for quantum photonic applications. JCMsuite was used to perform numerical simulations to optimize the cavity geometry, including the dimensions and periodicity of elliptical holes. These simulations predicted a high photon coupling efficiency of nearly 70% and a Purcell factor of approximately 28 for the optimized structure.
