Lensing and enhanced single atom detection via a single-pixel nanostructure
Ling-Xiao Wang, Lei Xu, Ai-Ping Liu +7
We propose and demonstrate a general mechanism for nanoscale lensing based on the phase gradient imposed by a single nanostructure scattering light in its near-field. We verify thi…
A re-entrant chip-free-space photonic interface for telecom-to-Rubidium spectroscopy
Jia-Lin Chen, Ruixin Zhou, Deng-Hong Liu +13
Photonic integrated circuits (PICs) generate, route, and process light with high efficiency, scalability, and functional density on a single chip. Yet the tightly confined on-chip…
Multifunctional metalens for trapping and characterizing single atoms
Guang-Jie Chen, Dong Zhao, Zhu-Bo Wang +10
Precise control and manipulation of neutral atoms are essential for quantum technologies but largely dependent on conventional bulky optical setups. Here, we demonstrate a multifun…
Proposal of a free-space-to-chip pipeline for transporting single atoms
Aiping Liu, Jiawei Liu, Zhanfei Kang +6
A free-space-to-chip pipeline is proposed to efficiently transport single atoms from a magneto-optical trap to an on-chip evanescent field trap. Due to the reflection of the dipole…
Transporting cold atoms towards a GaN-on-sapphire chip via an optical conveyor belt
Lei Xu, Ling-Xiao Wang, Guang-Jie Chen +8
Trapped atoms on photonic structures inspire many novel quantum devices for quantum information processing and quantum sensing. Here, we have demonstrated a hybrid photonic-atom ch…
Proposal for stable atom trapping on a GaN-on-Sapphire chip
Aiping Liu, Lei Xu, Xin-Biao Xu +6
The hybrid photon-atom integrated circuits, which include photonic microcavities and trapped single neutral atom in their evanescent field, are of great potential for quantum infor…
Multi-grating design for integrated single-atom trapping, manipulation, and readout
Aiping Liu, Jiawei Liu, Wei Peng +5
An on-chip multi-grating device is proposed to interface single-atoms and integrated photonic circuits, by guiding and focusing lasers to the area with ~10um above the chip for tra…
Reconfigurable vortex beam generator based on the Fourier transformation principle
Aiping Liu, Chang-Ling Zou, Xifeng Ren +4
A method to generate the optical vortex beam with arbitrary superposition of different orders of orbital angular momentum (OAM) on a photonic chip is proposed. The distributed Four…
On-chip generation and control of the vortex beam
Aiping Liu, Chang-Ling Zou, Xifeng Ren +2
A new method to generate and control the amplitude and phase distributions of a optical vortex beam is proposed. By introducing a holographic grating on top of the dielectric waveg…
Detecting orbital angular momentum through division-of-amplitude interference with a circular plasmonic lens
Ai-Ping Liu, Xiao Xiong, Xi-Feng Ren +5
We demonstrate a novel detection scheme for the orbital angular momentum (OAM) of light using circular plasmonic lens. Owing to a division-of-amplitude interference phenomenon betw…
Exciton-Plasmon-Photon Conversion in silver nanowire: polarization dependence
Lu-Lu Wang, Xi-Feng Ren, Ai-Ping Liu +4
Polarization dependence of the exciton-plasmon-photon conversion in silver nanowire-quantum dots structure was investigated using a scanning confocal microscope system. We found th…
Interference of surface plasmon polaritons from a "point" source
Xifeng Ren, Aiping Liu, Changling Zou +5
The interference patterns of the surface plasmon polaritons(SPPs) on the metal surface from a "point" source are observed. These interference patterns come from the forward SPPs an…
