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…
Aluminum nitride as a new material for chip-scale optomechanics and nonlinear optics
Chi Xiong, Wolfram H. P. Pernice, Xiankai Sun +3
Silicon photonics has offered a versatile platform for the recent development of integrated optomechanical circuits. However, silicon is limited to wavelengths above 1100 nm and do…
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…
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…
Integrated high frequency aluminum nitride optomechanical resonators
Chi Xiong, Xiankai Sun, King Y. Fong +1
Aluminum nitride (AlN) has been widely used in microeletromechanical resonators for its excellent electromechanical properties. Here we demonstrate the use of AlN as an optomechani…
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…
