Coupling Ideality of Integrated Planar High-Q Microresonators

Tobias Kippenberg, Martin Hubert Peter Pfeiffer, Michael Wolfgang Geiselmann, Junqiu Liu

Chip-scale optical microresonators with integrated planar optical waveguides are useful building blocks for linear, nonlinear, and quantum-optical photonic devices alike. Loss reduction through improving fabrication processes results in several integrated ...

Intermode Breather Solitons in Optical Microresonators

Tobias Kippenberg, Martin Hubert Peter Pfeiffer, Erwan Guillaume Albert Lucas, John David Jost, Michael Wolfgang Geiselmann, Maxim Karpov, Hairun Guo, Junqiu Liu, Miles Henry Anderson

Dissipative solitons can be found in a variety of systems resulting from the double balance between dispersion and nonlinearity, as well as gain and loss. Recently, they have been observed to spontaneously form in Kerr nonlinear microresonators driven by a ...

Frequency-comb-assisted broadband precision spectroscopy with cascaded diode lasers

Tobias Kippenberg, Martin Hubert Peter Pfeiffer, Victor Brasch, Arne Kordts, Michael Wolfgang Geiselmann, Hairun Guo, Junqiu Liu

Frequency-comb-assisted diode laser spectroscopy, employing both the accuracy of an optical frequency comb and the broad wavelength tuning range of a tunable diode laser, has been widely used in many applications. In this Letter, we present a novel method ...

Coupling Ideality of Integrated Silicon Nitride Microresonators for Nonlinear Photonics

Tobias Kippenberg, Martin Hubert Peter Pfeiffer, Victor Brasch, Arne Kordts, Maxim Karpov, Hairun Guo, Junqiu Liu

Integrated microresonators are essential building blocks of linear and nonlinear photonic devices. Here we show that the performance of high-Q silicon nitride microresonators for nonlinear photonics strongly depends on the ideality of their coupler design. ...

Study of chi(cJ) decaying into phi K*(892)(K)over-bar

François Bianchi, Jun Dong, Jiannong Fang, Hua Zhang, Mingkui Wang, Fang Liu, Yixing Chen, Shan Jin, Xiaoqing Zhou, Yuan Yuan, Fengping Li, Qian Wang, Lei Zhou, Sofia Carmen Suzanne Spataro, Zhirui Xu, Lin Yang, Ke Liu, Yu Zheng, Siyuan Wang, Junqiu Liu, Yi Zhang, Jianing Li, Lei Zhang, Yong Yang, Hao Liu, Jian Liu, Yang Qin, Feng Liu, Xuan Li, Lei Li, Kun Liu, Cheng Li, Xiao Wang, Yi Wang, Xin Chen, Wei Li, Jie Chen, Yifei Guo, Shuai Liu, Zheng Wang, Qianyu Zhao

Using a data sample of 106 million psi(3686) events collected with the BESIII detector operated at the BEPCII storage ring, we study for the first time the decays chi(cJ) -> phi(KSK +/-)-K-0 pi(-/+) and chi(cJ) -> phi K+K-pi(0) in the E1 radiative transiti ...

High-precision x-ray FEL pulse arrival time measurements at SACLA by a THz streak camera with Xe clusters

Leonid Rivkin, Christoph Peter Hauri, Ishkhan Gorgisyan, Rasmus Ischebeck, Junqiu Liu

The accurate measurement of the arrival time of a hard X-ray free electron laser (FEL) pulse with respect to a laser is of utmost importance for pump-probe experiments proposed or carried out at FEL facilities around the world. This manuscript presents the ...

Generation of OH radicals at palladium oxide nanoparticle modified electrodes, and scavenging by fluorescent probes and antioxidants

Hubert Girault, Junqiu Liu

The reduction of palladium oxide nanoparticles in the presence of hydrogen peroxide or dissolved oxygen gives rise to a catalytic reduction current dependent on the hydrogen peroxide concentration or the oxygen concentration. Using terephthalic acid as an ...
