Figure 1

Illustration of (a) spherical and (b) cylindrical silicon resonators of radius R. The cylindrical body has a heigh \(h = 2R\). A conical well with angle \(\alpha \) and centered apex is additionally drilled in the sphere and cylinder. Note that the well apex lies at the origin of the transverse plane \(z=0\). In (c) and (d) we represent a meridional section (xz-plane) of the solid of revolution shown in (a) and (b), respectively. A MD point source is set in the z-axis of revolution, also oscillating along the z direction, which is inserted in the tapered angle well at a distance d from the center of the resonators.
