Hydrodynamic Insight Drives Multimodal Light_Field Dynamics via Streamline Engineering
Wenxiang Yan, Zheng Yuan, Yuan Gao +5
Since the 1970s, analogies between laser dynamics and fluid systems have provided insight into phenomena such as chaos, multistability, and turbulence. Building on this perspective…
Vortex-Free Intrinsic Orbital Angular Momentum
Wenxiang Yan, Zheng Yuan, Yuan Gao +5
Optical orbital angular momentum (OAM) has traditionally relied on vortex beams with helical phase fronts imparting quantized intrinsic OAM. Here, we introduce a fundamentally vort…
Controlling Enhancement of Transmitted Goos-Hänchen Shifts: From Symmetric to Unidirectional
Zhuolin Wu, Weiming Zhen, Zhi-Cheng Ren +3
Since the discovery of the Goos-Hänchen (GH) shift in the 1940s, its deep connections to Fourier transforms and causality have led to widespread interest and applications in optic…
Observation of High-Order Quantum Pancharatnam-Berry Phase with Structured Photons
Shuang-Yin Huang, He Jiang, Zhi-Cheng Ren +6
When a quantum system evolves so that it returns to its initial state, it will acquire a geometric phase acting as a memory of the transformation of a physical system, which has be…
Postselection-Free Cavity-Enhanced Narrow-Band Orbital Angular Momentum Entangled Photon Source
Pei Wan, Wen-Zheng Zhu, Yan-Chao Lou +5
Cavity-enhanced spontaneous parametric down-conversion (SPDC) provides a significant way to produce 10 MHz narrow-band photon pairs, which matches the bandwidth of photon for…
Two-particle quantum interference in a nonlinear optical medium: a witness of timelike indistinguishability
Chao Chen, Shu-Tian Xue, Yu-Peng Shi +8
The Hong-Ou-Mandel effect is a paradigmatic quantum phenomenon demonstrating the interference of two indistinguishable photons that are linearly coupled at a 50:50 beam splitter. H…
