Figure 1

(a) Sketch of the experimental setup of the optical cavity and the dynamic mode AFM. (b) A scanning electron microscope (SEM) image showing the bottom view of a rectangular cantilever with a gold-coated glass sphere glued on its front end. (c) An AFM image showing a periodic array of gold disks of diameter d = 650 nm on a quartz substrate. The viewing area is 5 × 5 μm2.
