Achromatic Petal‐Shaped Beam Generation and Information Encoding Based on Perfect Vortex Beam

Nanophotonics, Volume 15, Issue 10, 27 May 2026.
Based on petal‐shaped beams with controllable topological charge, size, and rotation angle, this work employs a spatially multiplexed all‐dielectric TiO2 transmissive array to numerically achieve achromatic petal‐shaped beams at three wavelengths: 480 nm, 530 nm, and 630 nm. Leveraging their unique intensity distribution and rotational characteristics,

Deep Learning Enabled Ultrafast Optical Spectral Phase Retrieval via Unbalanced‐Intensity Autocorrelation

Nanophotonics, Volume 15, Issue 10, 27 May 2026.
Phase‐enabled nonlinear gating with unbalanced intensity (PENGUIN) enables reconstruction of the complete ultrafast optical field from one‐dimensional nonlinear interferometric autocorrelation traces. Combined with deep learning, the DeepPENGUIN framework enables real‐time spectral phase retrieval without spectrally resolved detection or iterative ...
