Large-Area Superconducting Nanowire Single-Photon Detector with Double-Stage Avalanche Structure
Risheng Cheng, Menno Poot, Xiang Guo +2
We propose a novel design of superconducting nanowire avalanche photodetectors (SNAPs), which combines the advantages of multi-stage avalanche SNAPs to lower the avalanche current…
Broadband frequency conversion via adiabatically tapered waveguide in photonic integrated circuits
Xiao Xiong, Chang-Ling Zou, Xiang Guo +3
We propose to use the integrated aluminum nitride waveguide with engineered width variation to achieve optical frequency conversion based on nonlinear effect on a photoni…
Characterization of optical quantum circuits using resonant phase shifts
Menno Poot, Hong X. Tang
We demonstrate that important information about linear optical circuits can be obtained through the phase shift induced by integrated optical resonators. As a proof of principle, t…
Low loss spin wave resonances in organic-based ferrimagnet vanadium tetracyanoethylene thin films
Na Zhu, Xufeng Zhang, I. H. Froning +3
We experimentally demonstrate high quality factor spin wave resonances in an encapsulated thin film of the organic-based ferrimagnet vanadium tetracyanoethylene (V[TCNE]$_\textit{x…
Noise-free quantum optical frequency shifting driven by mechanics
Linran Fan, Chang-Ling Zou, Menno Poot +4
The ability to manipulate single photons is of critical importance for fundamental quantum optics studies and practical implementations of quantum communications. While extraordina…
Multimode Strong Coupling in Superconducting Cavity Piezo-electromechanics
Xu Han, Chang-Ling Zou, Hong X. Tang
High frequency mechanical resonators subjected to low thermal phonon occupancy are easier to be prepared to the ground state by direct cryogenic cooling. Their extreme stiffness, h…
