Propagation Dynamics of Photonic Toroidal Vortices Mediated by Orbital Angular Momenta
Xin Liu, Nianjia Zhang, Qian Cao +4
The dynamics of vortex rings in fluids have long captivated researchers due to the intriguing complexity of their behavior, despite the apparent simplicity of their structure. In o…
Topological links and knots of speckled light mediated by coherence singularities
Zhuoyi Wang, Xingyuan Lu, Zhigang Chen +2
Links and knots are exotic topological structures that have garnered significant interest across multiple branches of natural sciences. Coherent links and knots, such as those cons…
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…
Spatial coherence measurement and partially coherent diffractive imaging
Yifeng Shao, Xingyuan Lu, Sander Konijnenberg +3
The complete characterization of spatial coherence is difficult because the mutual coherence function is a complex-valued function of four independent variables. This difficulty li…
