A scanning-electron-microscopy image of the fiber-top cantilever (before the evaporation of the silver layer). Dimensions: , , .
Schematic view of the readout technique. The continuous arrow represents the input light. Dashed arrows represent the light reflected at the fiber-to-air, air-to-cantilever, and cantilever-to-metal interfaces. The shaded area represents the core of the fiber (not to scale).
(Color online) Readout output signal obtained in correspondence of a mechanical deformation of the cantilever. Images were obtained with an optical microscope and represents the different positions in which the cantilever has been set: (i) freely suspended (before contact), (ii) in contact with the edge of the optical fiber, and (iii) freely suspended (after contact).
Readout output signal as a function of the temperature of the cantilever.
