Near-field cavity optomechanical coupling in a compound semiconductor nanowire

[摘要] Coupling submicrometer mechanical elements such as nanowires to optical cavities is technically challenging because of the size difference between the resonators. Here, the authors demonstrate cavity optomechanical coupling of a nanowire mechanical resonator to an optical microsphere through near-field evanescent gradient forces and fine-tuning of resonance properties.
