The spectral characteristics of a microdisk in a diamond substrate with metal gates are simulated. It is shown that the radiative quality factor of a microdisk depends on the parameters of the substrate and the gates. Q-factor oscillations are detected with increasing distance between the disk and the substrate. The spectroscopic response of a microdisk with an NV center is obtained, and the effect of the substrate and the gates on the signal-to-noise (S/N) ratio of this system is studied. It is shown that this ratio can be significantly increased by selecting the structure’s parameters so that the radiative Q factor is maximum.
