Figure 6: Measured quality (Q) factors of multimode SiC microdisk resonators.
From: Spatial mapping of multimode Brownian motions in high-frequency silicon carbide microdisk resonators
The measured Qs are plotted against (a) f-values and (b) (a−b)/b, with modes coded in symbol shapes and different devices coded in colours. The shaded regions are the resonance modes that appear to experience more asymmetric effects (for example, exhibiting more asymmetric mode shapes, see Fig. 4). Dashed lines in a show contours of the figure of merit f × Q and the dashed line in b is Q ~[(a−b)/b]1/3. (c) Measured Qs with varying pedestal size (thus b/a) and frequency for five devices all with same diameter a=29.5 μm. The projection of this thee-dimensional plot in the f−b/a plane reproduces Fig. 5b, with identical colour coding (for all the mode shapes). Cubes (corresponding to squares in Fig. 5b) represent the resonant modes experiencing more asymmetric effects.
