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 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…
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…
Three-dimensional abruptly autofocusing by counter-propagating Airy pulses with radial Airy beam profile
Youngbin Park, Xiaolin Su, Qian Cao +1
We report the experimental observation of a three-dimensional abruptly autofocusing effect by synthesizing a radially distributed Airy beam with two counter-propagating Airy pulses…
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…
Spatiotemporal Photonic Emulator of Potential-free Schrödinger Equation
Qian Cao, Nianjia Zhang, Andy Chong +1
Photonic quantum emulator utilizes photons to emulate the quantum physical behavior of a complex quantum system. Recent study in spatiotemporal optics has enriched the toolbox for…
