title = "Theoretical and experimental study of radiation pressure-induced mechanical oscillations (parametric instability) in optical microcavities",
abstract = "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 ultra-high-Q microtoroids. Embodied within a microscale, chip-based device, this mechanism can benefit both research into macroscale quantum mechanical phenomena and improve the understanding of the mechanism within the context of laser interferometer gravitational-wave observatory (LIGO). It also suggests that new technologies are possible that will leverage the phenomenon within photonics.",

Digital Object Identifier 10.1109/JSTQE.2005.862890 Fig. 1. Illustration of the radiation pressure-induced optomechanical coupling mechanism. Binω, the input optical field (at frequency ω close to a resonant frequency of the cavity ω0) to the Fabry–Perot causes large circulating field Aω as a result of resonant power buildup in the cavity. The pressure caused by this power moves the free-to-move cavity wall by x, modeled as a damped harmonic oscillator at frequency Ω. Motion of the end mirror, on the other hand, causes frequency change of the Fabry–Perot resonant optical mode. This interaction at sufficient optical powers results in regenerative oscillations of the end mirror and, consequently, the modulation of the output optical power Boutω.",
