(a) Experimental setup. VOA: variable optical attenuator; PC: polarization controller; PD: photodetector; ESA: electrical spectrum analyzer. A tapered fiber is used to couple light into the resonator, and it is parked on the nanostrings. The experiment is conducted under vacuum pressure of . (b) Experimentally recorded cavity transmission (blue circle) with theoretical fitting (red line) for an optical mode at wavelength 1552.647 nm. .

FIG. 3.

RF spectrum of the first two flapping modes (a) and the fundamental radial breathing mode (b). The subsets show the mechanical mode profiles at frequencies , and . The noise background is higher at low frequency region due to the 1/f noise in the ESA.

Image of FIG. 4.
FIG. 4.

(a) RF spectrum of the first three flapping modes, harmonics of the second flapping mode, and the mixed frequency components. The subset shows the mode profile for . (b) RF spectrum of radial breathing mode with two sidebands as a result of frequency mixing.

FIG. 5.

RF spectrum of the harmonics of the second flapping mode (a) and the mixed frequencies around the fundamental radial breathing mode (b).
