Low Power Resonant Optical Excitation of an Optomechanical Cavity

, 2010
We demonstrate the actuation of a double beam opto-mechanical cavity with a sinusoidally varying optical input power. We observe the driven mechanical motion with only 200 nW coupled to the optical cavity mode.

Noise suppression of on-chip mechanical resonators by chaotic coherent feedback

, 2015
We propose a method to decouple the nanomechanical resonator in optomechanical systems from the environmental noise by introducing a chaotic coherent feedback loop. We find that the chaotic controller in the feedback loop can modulate the dynamics of the
