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…
