a Distribution of elastic energy density of a mode of the diamond cavity resonant at ωp/(2π) = 2 GHz. The cavity geometry is artificially distorted along the coordinate of the mechanical mode for emphasis. The energy density is concentrated in the central part of the cavity. b Calculated coupling rate gorb in the phononic cavity. c Normalized amplitude of the optical electric field at vacuum wavelength λopt = 732 nm of an optical mode of the diamond cavity of an optical quality factor Qopt ≈ 106. The electric field is concentrated around the center of the cavity and thus overlaps with the regions providing high values of gorb. Scale bars: (a) 350 nm, (b) 350 nm (top), and 500 nm (bottom).
