Experimental Observation of Ghost Image Revivals via Structured Coherence
Weining Wang, Yaning Zhou, Sergey A Ponomarenko +2
Ghost imaging retrieves an object's image from intensity correlations between two light beams, neither of which independently carries information about the object. However, convent…
Radially correlated partially coherent beams with a deterministic vortex structure
Xinru Lian, Yaning Zhou, Xin Liu +7
Partially coherent beams have attracted considerable attention due to their intrinsic resilience against complex environmental perturbations. However, the intrinsic wavefront fluct…
Abnormal motions of optical vortex-antivortex-coupled wavepackets in the parabolic potential
Haolin Lin, Junhui Jia, Chunhao Liang +4
The paper investigates how vortex‑antivortex interactions within optical wavepackets confined by a parabolic potential lead to abnormal, non‑harmonic motions, demonstrating these e…
Source coherence orchestrates nonlinear random wave revivals
Yanlin Bai, Tianyu Cao, Pujuan Ma +4
We demonstrate that the Talbot length of periodic wave packets, long believed to be solely determined by their periodicity, is strongly affected by the source coherence in the nonl…
General framework for incoherent topological structured light and optical information encoding
Ao Zhou, Dong Xu, Yaning Zhou +8
Topology provides a powerful language for describing global invariants in physical systems, yet optical topology has been explored predominantly with fully coherent light. Recent s…
Regular and irregular revivals of quasi-periodic random waves
Yanlin Bai, Yangjian Cai, Chunhao Liang +1
Paraxial wave packets with discrete spatial, temporal, or spatiotemporal spectra are known to undergo periodic axial revivals on propagation in either free space or linear transpar…
