Recovering topological information of light by topological learning
Benquan Wang, Trishita Das, Yuhan Peng +8
The evolution of modern-day communication networks towards optical solutions with enhanced capacity and robustness is driving interest in topological light waves, exploiting their…
Structured Harmonic Generation via Geometric Phase Enabled Pump Shaping
Ting-Ting Liu, Shi-Hui Ding, Chun-Yu Li +4
Nonlinear optics is crucial for shaping the spatial structure of shortwave light and its interactions with matter, but achieving this through simple harmonic generation with a sing…
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…
