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…
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…
Ultrafast bursts of tailored spatiotemporal vortex pulses
Xin Liu, Chunhao Liang, Qian Cao +2
Orbital angular momentums (OAMs) of light can be categorized into longitudinal OAM (L-OAM) and transverse OAM (T-OAM). Light carrying time-varying L-OAM, known as self-torqued ligh…
