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…
A 1.16-μm-radius disk cavity in a sunflower-type circular photonic crystal with ultrahigh quality factor
Xufeng Zhang, Xiankai Sun, Hong X. Tang
We present a 1.16-\mum-radius disk cavity with ultrahigh quality (Q) factor by embedding the disk into a sunflower-type circular photonic crystal (CPC). The band gap of the CPC red…
High-Q silicon optomechanical microdisk resonators at gigahertz frequencies
Xiankai Sun, Xufeng Zhang, Hong X. Tang
We report disk-shaped silicon optomechanical resonators with frequency up to 1.75 GHz in the ultrahigh frequency band. Optical transduction of the thermal motion of the disks' in-p…
