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…
Second harmonic generation in phase matched aluminum nitride waveguides
W. H. P. Pernice, C. Xiong, C. Schuck +1
We demonstrate second order optical nonlinearity in aluminum nitride on insulator substrates. Using sputter-deposited aluminum nitride thin films we realize nanophotonic waveguides…
High-Q aluminum nitride photonic crystal nanobeam cavities
W. H. P. Pernice, C. Xiong, C. Schuck +1
We demonstrate high optical quality factors in aluminum nitride (AlN) photonic crystal nanobeam cavities. Suspended AlN photonic crystal nanobeams are fabricated in sputter-deposit…
Frequency and phase noise of ultra-high Q silicon nitride nanomechanical resonators
King Y. Fong, Wolfram H. P. Pernice, Hong X. Tang
We describe the measurement and modeling of amplitude noise and phase noise in ultra-high Q nanomechanical resonators made from stoichiometric silicon nitride. With quality factors…
