Polygonal Spatiotemporal Optical Vortices Wavepackets with Prescribed Vortex Structure
Haifa Fan, Qian Cao, Andy Chong +1
Optical vortices carrying orbital angular momentum offer additional degrees of freedom. According to the orientation of orbital angular momentum, optical vortices can be classified…
Spatiotemporal Topological Combs for Robust High-Dimensional Information Transmission
Dawei Liu, Daijun Luo, Huiming Wang +8
Sculpting light across its independent degrees of freedom-from orbital angular momentum to the discrete wavelengths of optical frequency combs-has unlocked vast communication bandw…
Spatiotemporal coupled Airy-Airy wavepacket and its propagation dynamics
Zhaofeng Huang, Xiaolin Su, Qian Cao +2
Airy beams, celebrated for their self-acceleration, diffraction-free propagation, and self-healing properties, have garnered significant interest in optics and photonics, with appl…
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…
Full space-time abrupt autofocusing spherical Airy wavepacket
Qian Cao, Nianjia Zhang, Chenghao Li +2
The ability to precisely focus optical beams is crucial for numerous applications, yet conventional Gaussian beams exhibit slow intensity transitions near the focal point, limiting…
Spatiotemporal Airy rings wavepackets
Xiaolin Su, Andy Chong, Qian Cao +1
Airy waves, known for their non-diffracting and self-accelerating properties, have been extensively studied in spatial and temporal domains, but their spatiotemporal (ST) counterpa…
