Theoretical and experimental study of radiation pressure-induced mechanical oscillations (parametric instability) in optical microcavities
IEEE Journal of Selected Topics in Quantum Electronics
Radiation pressure can couple the mechanical modes of an optical cavity structure to its optical modes, leading to parametric oscillation instability. This regime is characterized by regenerative oscillation of the mechanical cavity eigenmodes. Here, we present the first observation of this effect with a detailed theoretical and experimental analysis of these oscillations in ultrahigh-Q microtoroids. Embodied within a microscale, chip-based device, this mechanism can benefit both research intodoi:10.1109/jstqe.2005.862890 fatcat:qkrxsvbwynb7dgoyomxlaecmp4
