Photon-efficient optical tweezers via wavefront shaping. [PDF]
Sci AdvOptical tweezers enable noncontact trapping of microscale objects using light. It is not known how tightly it is possible to three-dimensionally (3D) trap microparticles with a given photon budget. Reaching this elusive limit would enable maximally stiff particle trapping for precision measurements on the nanoscale and photon-efficient tweezing of ...

Programming balanced optical beam splitters in white paint [PDF]
, 2014 Wavefront shaping allows for ultimate control of light propagation in multiple-scattering media by adaptive manipulation of incident waves. We shine two separate wavefront-shaped beams on a layer of dry white paint to create two enhanced output speckle ...

Model-based wavefront shaping microscopy [PDF]
Optics Letters, 2020 Wavefront shaping is increasingly being used in modern microscopy to obtain high-resolution images deep inside inhomogeneous media. Wavefront shaping methods typically rely on the presence of a “guide star” to find the optimal wavefront to mitigate the scattering of light. However, the use of guide stars poses severe limitations.

Wavefront shaping for forward scattering
Optics Express, 2022 Aberrations and scattering limit the ability of optical microscopy to penetrate deep tissues. Adaptive optics (AO) is a very effective technique to correct for smooth aberrations. Wavefront shaping (WFS) techniques, on the other hand, compensate both scattering and aberrations and have guaranteed convergence even for finding high-dimensional ...
