High-sensitivity monitoring of micromechanical vibration using optical whispering gallery mode resonators
High-sensitivity monitoring of micromechanical vibration using optical whispering gallery mode resonators
The inherent coupling of optical and mechanical modes in high finesse optical microresonators provides a natural, highly sensitive transduction mechanism for micromechanical vibration. Using homodyne and polarization spectroscopy techniques, we achieve shot-noise limited displacement sensitivities of . In an unprecedented manner, this enables the detection and study of a variety …
