摘要：

We present an optomechanical displacement transducer that relies on three cavity modes parametrically coupled to a mechanical oscillator and whose frequency spacing matches the mechanical resonance frequency. The additional resonances allow us to reach the standard quantum limit at a substantially lower input power (compared to the case of only one resonance), as both sensitivity and quantum backaction are enhanced.
