Coherent control of the resonant response in spatially extendedoptomechanical structures is complicated by the fact that the optical drive isaffected by the back-action from the generated phonons. Here we report a newapproach to coherent control based on stimulated Raman-like scattering, inwhich the optical pressure can remain unaffected by the induced vibrations evenin the regime of strong optomechanical interactions. We demonstrateexperimentally coherent control of flexural vibrations simultaneously along thewhole length of a dual-nanoweb fiber, by imprinting steps in the relative phasebetween the components of a two-frequency pump signal,the beat frequency beingchosen to match a flexural resonance. Furthermore, sequential switching of therelative phase at time intervals shorter than the lifetime of the vibrationsreduces their amplitude to a constant value that is fully adjustable by tuningthe phase-modulation depth and switching rate. The results may trigger newdevelopments in silicon photonics, since such coherent control uniquelydecouples the amplitude of optomechanical oscillations from power-dependentthermal effects and nonlinear optical loss.
