Quantum Cross Nonlinearity for Photon-Number-Resolving Nondestructive Detection
Jiang-Shan Tang, Mingyuan Chen, Miao Cai +4
We present an unconventional mechanism for quantum nonlinearity in a system comprising of a V-type quantum emitter (QE) and two Fabry-Perot cavities. The two transitions of the V-t…
Dynamic Nonreciprocity with a Kerr Nonlinear Resonator
Rui-Kai Pan, Lei Tang, Keyu Xia +1
On-chip optical nonreciprocal devices are vital components for integrated photonic systems and scalable quantum information processing. Nonlinear optical isolators and circulators…
Nonreciprocal single-photon band structure
Jiangshan Tang, Wei Nie, Lei Tang +5
We study single-photon band structure in a one-dimensional (1D) coupled-resonator optical waveguide (CROW) which chirally couples to an array of two-level quantum emitters (QEs). T…
Single-photon transport in a whispering-gallery mode microresonator directionally coupled with a two-level quantum emitter
Jiangshan Tang, Lei Tang, Keyu Xia
We investigate the single-photon transport problem in the system of a Whispering-Gallery mode microresonator directionally coupled with a two-level quantum emitter (QE). This QE-mi…
Quantum Squeezing Induced Optical Nonreciprocity
Lei Tang, Jiangshan Tang, Mingyuan Chen +3
We propose an all-optical approach to achieve optical nonreciprocity on a chip by quantum squeezing one of two coupled resonator modes. By parametric pumping a nonlinear resonator…
Ultralow-power all-optical switching via a chiral Mach-Zehnder interferometer
Y. P. Ruan, H. D. Wu, S. J. Ge +8
All-optical switching increasingly plays an important role in optical information processing. However, simultaneous achievement of ultralow power consumption, broad bandwidth and h…
Towards On-Demand Heralded Single-Photon Sources via Photon Blockade
Jiangshan Tang, Lei Tang, Haodong Wu +7
Spontaneous parametric down-conversion (SPDC) in a laser pumped optical nonlinear medium can produce heralded single photons with a high purity but a very low yield. Improving the…
Quantum Tomography of the Photon-Plasmon Conversion Process in a Metal Hole Array
Lei Tang, Kaimin Zheng, Jiale Guo +8
In the past decades, quantum plasmonics has become an active area due to its potential applications in on-chip plasmonic devices for quantum information processing. However, the fu…
On-Chip Chiral Single-Photon Interface: Isolation and Unidirectional Emission
Lei Tang, Jiangshan Tang, Weidong Zhang +5
Chiral quantum systems have received intensive attention in fundamental physics and applications in quantum information processing including optical isolation and photon unidirecti…
