Abstract :
We use evanescent near-fields of high-Q optical microresonators to extend cavity-optomechanical coupling to nanomechanical oscillators. Pure radiation pressure coupling to SiN nanomechanical strings is demonstrated. Dynamical backaction allows creating laser-like nanomechanical oscillation at nanowatt threshold.
