Optical interferometry resonance measurement results for Devices #1 and #2. (a) Colored scanning electron microscope (SEM) image of Device #1. (b) and (c) Measured thermomechanical noise spectrum and photothermally driven resonance spectrum of Device #1, respectively. (d) Colored SEM image of Device #2. (e) Measured thermomechanical motion spectrum of Device #2. Inset: Static reflectance mapping of device area. (f)–(i) Zoomed-in spectra of each resonance of Device #2 with insets showing the finite element method (FEM) simulated mode shape (left) and optical interferometric mapping of the spatially resolved device motion for each resonance mode (right). All scale bars are 10 μm.
