In previous reports, we have designed a bull's-eye cavity exhibiting a polarization-independent response and have successfully demonstrated its proof-of-principle experiment for realizing an efficient quantum interface using gate-defined quantum dots formed in GaAs quantum wells. In this report, we show that further enhancement of efficiency is possible by simply adjusting the thickness of the air gap between the substrate and the cavity.
