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…
Casimir Force and In Situ Surface Potential Measurements on Nanomembranes
Daniel Garcia-Sanchez, King Yan Fong, Harish Bhaskaran +2
We present Casimir force measurements in a sphere-plate configuration that consists of a high quality nanomembrane resonator and a millimeter sized gold coated sphere. The nanomemb…
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…
High Q micro-ring resonators fabricated from polycrystalline aluminum nitride films for near infrared and visible photonics
Wolfram H. P. Pernice, Chi Xiong, Hong X. Tang
We demonstrate wideband integrated photonic circuits in sputter-deposited aluminum nitride (AlN) thin films. At both near-infrared and visible wavelengths, we achieve low propagati…
