A representation of the experimental setup including (a) sketch of front view showing aluminum mounting frame (b) zoomed in view through transparent cantilever at optical fibers (c) photo showing the glass cantilever mechanically clamped between the aluminum block and the aluminum mounting frame, and (d) schematic of the optical components and vacuum chamber. The lever is approximately 11 mm long, 2 mm in width, and about 80 μm in thickness.
The swept sine response of the lever at its fundamental flexural resonance to a 6.5 mW rms optical driving signal. The discrete points denote the experimental data whereas the smooth curve denotes the model fit.
Dynamic properties for the first two eigenmodes (n = 1, n = 2) of the cantilever.
Measured values of stiffness for the cantilever sensing element.
