- Abstract:
- An integrable on-chip displacement transduction of nanomechenical motion is developed that senses the modulation ofthe optical near-field of an illuminated vibrating string with a nearby Schottky photodiode. This scheme poses no restrictions onresonator material and avoids additional damping. The achieved sensitivity of 1 pm/Hz1/2enables the detection of Brownian motionof our mechanical resonators at room temperature. Implementing a feedback scheme of the detected signal into the electrical actu... »
