Talbot-like pattern evolution in complex structured light from unitary transformation
Zheng-Xiao Cao, Ting-Ting Liu, Bo-Zhao +3
Astigmatic unitary transformations allow for the adiabatic connections of all feasible states of paraxial Gaussian beams on the same modal sphere, i.e., Hermite-Laguerre-Gaussian (…

Structured Light Modal Interface via Liquid-Crystal Planar Optics
Chun-Yu Li, Si-Jia Liu, Hai-Jun Wu +6
Recent advances in planar optics with geometric-phase superstructures have brought a new paradigm in the control of structured light and, in particular, has substantially enhanced…

Single-shot, full characterization of the spatial wavefunction of light fields via Stokes tomography
Bing-Shi Yu, Hai-Jun Wu, Chun-Yu Li +5
Since the diffraction behavior of a light field is fully determined by its spatial wavefunction, i.e., its spatial complex amplitude (SCA), full characterization of spatial wavefun…
