Greatly enhanced intensity-difference squeezing for narrow-band quantum metrology applications
Da Zhang, Changbiao Li, Zhaoyang Zhang +4
Narrow-band intensity-difference squeezing beams have important applications in quantum metrology and gravitational wave detection. The best way to generate narrow-band intensity-d…
Analysis of a Triple-cavity Photonic Molecule Based on Coupled Mode Theory
Chao Yang, Yong Hu, Xiaoshun Jiang +1
In this paper, we analyze a chain-linked triple-cavity photonic molecule (TCPM) with controllable coupling strengths between the cavities on their spectral properties and field (en…
Unveiling the link between fractional Schrödinger equation and light propagation in honeycomb lattice
Da Zhang, Yiqi Zhang, Zhaoyang Zhang +5
We establish a link between the fractional Schrödinger equation (FSE) and light propagation in the honeycomb lattice (HCL) - the Dirac-Weyl equation (DWE). The fractional Laplacian…
Transport properties in the photonic super-honeycomb lattice - a hybrid fermionic and bosonic system
Hua Zhong, Yiqi Zhang, Yi Zhu +6
We report on transport properties of the super-honeycomb lattice, the band structure of which possesses a flat band and Dirac cones, according to the tight-binding approximation. T…
Observation of electromagnetically induced Talbot effect in an atomic system
Zhaoyang Zhang, Xing Liu, Dan Zhang +4
We experimentally demonstrate the Talbot effect resulting from the repeated self-reconstruction of a spatially intensity-modulated probe field under the Fresnel near-field regime.…
Demonstration of a Chip-based Nonlinear Optical Isolator
Shiyue Hua, Jianming Wen, Xiaoshun Jiang +3
Despite fundamentally challenging in integrated (nano)photonics, achieving chip-based light nonreciprocity becomes increasingly urgent in signal processing and optical communicatio…
