Spatial mode (de) multiplexing of orbital angular momentum (OAM) beams is a promising
solution to address future bandwidth issues, but the rapidly increasing divergence with the …

Structured lights, particularly those with tunable and controllable geometries, are highly
topical due to a myriad of their applications from imaging to communications. Ray-wave …

We report, for the first time to the best of our knowledge, a truncated diffraction with a
triangular aperture of the SU (2) geometric modes and propose a method to detect the …

We develop a novel method of creating optical vortex array by the conversion of a standing-
wave Laguerre-Gaussian (LG) mode. Theoretically, by employing the transformational …

The geometry of classical dynamics in coupled oscillators with SU (2) transformations is
explored and found to be relevant to a family of continuous-transformation orbits between …

Structured light, with its ability to tailor diverse degrees of freedom (DoFs) of light has
recently attracted increasing attention, especially as geometric beams that can open multiple …

High-power structured beams with the transverse morphologies as the Lissajous figures are
generated by an Nd: YVO_4 laser under two-dimensional off-axis pumping. By fine-tuning …

We interpret the intrinsic mechanism of the transition from geometric modes to eigenmodes
in the Gaussian wave-packet representation based on numerical simulation. We then …

Abstract The Fock–Darwin system is analyzed from the point of view of its symmetry
properties in the quantum and classical frameworks. The quantum Fock–Darwin system is …

We systematically explore the power scale-up and propagation evolution of Lissajous
structured beams in a lowly Nd-doped YVO 4 laser with the off-axis pumping scheme. We …
