Geometric phase-space nonseparability triggers giant optical shifts
Kaiqi Zhu, Yonglei Liu, Yao Zhao +8
Nonseparability among multiple degrees of freedom has enabled fundamental advances in structured light and related applications. Here we unveil a previously overlooked form of nons…
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…
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…
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…
Wigner picture of partially coherent accelerating beams
Sergey A. Ponomarenko, Morteza Hajati
We advance a phase-space theory of partially coherent accelerating, non-diffracting beams employing the Wigner distribution function (WDF). We derive a general expression for the W…
Spatiotemporally Localized Optical Links and Knots
Yaning Zhou, Nianjia Zhang, Ao Zhou +7
Optical links and knots have attracted growing attention owing to their exotic topologic features and promising applications in next-generation information transfer and storage. Ho…
