Backaction limits on self-sustained optomechanical oscillations
M. Poot, K. Y. Fong, M. Bagheri +2
The maximum amplitude of mechanical oscillators coupled to optical cavities are studied both analytically and numerically. The optical backaction on the resonator enables self-sust…
A superhigh-frequency optoelectromechanical system based on a slotted photonic crystal cavity
Xiankai Sun, Xufeng Zhang, Menno Poot +2
We develop an all-integrated optoelectromechanical system that operates in the superhigh frequency band. This system is based on an ultrahigh-Q slotted photonic crystal (PhC) nanoc…
Dispersive coupling and optimization of femtogram L3-nanobeam optomechanical cavities
Jiangjun Zheng, Xiankai Sun, Ying Li +4
We present the design of a femtogram L3-nanobeam photonic crystal cavity for optomechanical studies. Two symmetric nanobeams are created by placing three air slots in a silicon pho…
Femtogram Doubly Clamped Nanomechanical Resonators Embedded in a High-Q Two-Dimensional Photonic Crystal Nanocavity
Xiankai Sun, Jiangjun Zheng, Menno Poot +2
We demonstrate a new optomechanical device system which allows highly efficient transduction of femtogram nanobeam resonators. Doubly clamped nanomechanical resonators with mass as…
