Plasmonic-enhanced bright single spin defects in silicon carbide membranes
Ji-Yang Zhou, Qiang Li, Zhi-He Hao +10
Optically addressable spin defects in silicon carbide (SiC) have emerged as attractable platforms for various quantum technologies. However, the low photon count rate significantly…
High-efficiency broadband fiber-to-chip coupler using a 3D nanoprinting microfiber
Dong-Hui Fan, Xing-Yu Zhang, Wei-Jun Zhang +6
We propose a method for coupling a tapered optical fiber to an inverted tapered SiN waveguide by fabricating a microfiber using 3D nanoprinting lithography. The microfiber consists…
A photon counting reconstructive spectrometer combining metasurfaces and superconducting nanowire single-photon detectors
Jingyuan Zheng, You Xiao, Mingzhong Hu +8
Faint light spectroscopy has many important applications such as fluorescence spectroscopy, lidar and astronomical observations. However, long measurement time limit its applicatio…
Long-distance thermal temporal ghost imaging over optical fibers
Xin Yao, Wei Zhang, Hao Li +3
A thermal ghost imaging scheme between two distant parties is proposed and experimentally demonstrated over long-distance optical fibers. In the scheme, the weak thermal light is s…
Large-sensitive-area superconducting nanowire single-photon detector at 850 nm with high detection efficiency
Hao Li, Lu Zhang, Lixing You +6
Satellite-ground quantum communication requires single-photon detectors of 850-nm wavelength with both high detection efficiency and large sensitive area. We developed superconduct…
Few-photon imaging at 1550 nm using a low-timing-jitter superconducting nanowire single-photon detector
H. Zhou, Y. He, L. You +5
We demonstrated a laser depth imaging system based on the time-correlated single-photon counting technique, which was incorporated with a low-jitter superconducting nanowire single…
