Customizable Fully Structured Vector Trajectory Beams in the Focal Plane via a Single‐Layer Metasurface

Nanophotonics, Volume 15, Issue 10, 27 May 2026.
This work introduces a unique class of structured light—trajectory beams—where all degrees of freedom evolve dynamically along the predefined trajectory. By employing computer‐generated holography, single‐layer metasurfaces achieve the complete decoupling of trajectory shape and the distributions of amplitude, phase, and polarization along the path ...

Adaptive optics for wavefront shaping and analysis

International Journal of Intelligent Systems Technologies and Applications, 2008
This brief address sees adaptive optics as a technology for wavefront and beam shaping in nearly real time by phase adaptation and compensation. It suggests that adaptive optics has great potential in the fields of beam shaping and wave front analysis. Advantages and applications are indicated.

Guidestar-free wavefront shaping

Frontiers in Optics / Laser Science, 2020
We present a new concept, image-guided wavefront-shaping, for non-invasive, widefield, incoherent imaging through highly scattering layers, without illumination control. We use image quality assessment as a feedback for wavefront correction.

Fast, precise, and shape-flexible registration of wavefronts

Applied Optics, 2021
A fast and precise algorithm for wavefront reconstruction by the registration of wavefront segments is presented. If the wavefront exceeds the sensor aperture or the dynamic range of the sensor, a Shack–Hartmann sensor can measure only segments of an optical wavefront. The algorithm registers the wavefront segments in parallel,

Metalasers with arbitrarily shaped wavefront

Nature
Integrated nanolasers have been explored for decades owing to their important role in many applications, ranging from optical information processing and communications to medical treatments1-6. Although polarization, orbital angular momentum and directivity of nanolasers have been successfully manipulated7-9, neither their laser wavefront nor radiation

Resonant wavefront-shaping metasurfaces

High Contrast Metastructures X, 2021
Diffractive photonic devices manipulate light via local and nonlocal optical modes. Local devices, such as metasurfaces, can shape a wavefront at multiple selected wavelengths, but inevitably modify light across the spectrum; nonlocal devices, such as grating filters, offer great frequency selectivity but limited spatial control.

Learning Optimal Wavefront Shaping for Multi-Channel Imaging

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2021
Fast acquisition of depth information is crucial for accurate 3D tracking of moving objects. Snapshot depth sensing can be achieved by wavefront coding, in which the point-spread function (PSF) is engineered to vary distinctively with scene depth by altering the detection optics.

Active wavefront shaping and analysis

SPIE Proceedings, 2005
Active and adaptive optics are becoming more important in the field of beam shaping and wave front analysis. One of the main reasons for the progress and recent activities in active optics is the availability of new active elements like deformable mirrors, micro mirrors and liquid crystals.

Wavefront shaping for intraocular scattering correction

OSA Imaging and Applied Optics Congress 2021 (3D, COSI, DH, ISA, pcAOP), 2021
In this work we propose a non-invasive alternative to cataracts surgery by means of manipulating the wavefront of the incident light. We show a two-fold improvement in the Strehl ratio of the ocular Point Spread Function.
