Mode conversion via wavefront shaping
Optics Express, 2018 In recent years, wavefront shaping has been utilized to control and correct distorted light for enhancing a bright spot, generation of a Bessel beam or darkening a complete area at the output of a scattering system. All these outcomes can be thought of as enhancing a particular mode of the output field. In this letter, we study the relation between the

Artificial intelligence-assisted light control and computational imaging through scattering media [PDF]
Journal of Innovative Optical Health Sciences, 2019 Coherent optical control within or through scattering media via wavefront shaping has seen broad applications since its invention around 2007. Wavefront shaping is aimed at overcoming the strong scattering, featured by random interference, namely speckle

Optical Cryptanalysis Method Using Wavefront Shaping
IEEE Photonics Journal, 2017 Optical techniques for information security have drawn a lot of attention in recent years. The development of cryptanalysis strategies will also have a positive promotion for the cryptosystems themselves.

Mesoscopic theory of optical wavefront shaping to focus deep inside opaque media [PDF]
EPJ Web of ConferencesWe describe the theory of optical wavefront shaping, where waves are focused to a predefined focal point deep inside a disordered three-dimensional (3D) opaque medium (e.g., tissue, paint, foam) by shaping the wavefield sent by N external array elements.

The Shapes of Clines and Wavefronts
Molecular EcologyABSTRACT Cline theory has a central place in speciation studies. Cline locations delimit taxon boundaries, cline widths scale with barrier strength, and the shapes of clines (smooth or stepped) suggest whether species barriers are mono‐ or polygenic.

, 2022 The holy grail of biomedical optical imaging is to perform microscopy deep inside living tissue. Biological tissue scatters light, which prevents the formation of a sharp focus. Wavefront shaping (WFS) makes it possible to focus light through or inside turbid media by spatially shaping the incident wavefront. In this thesis, we tackled some of the most

Deep learning assisted optical wavefront shaping in disordered medium
, 2019 Wavefront shaping (WFS) has been put forward several years ago to break the limitation caused by optical scattering in inhomogeneous medium, and realize optical focusing in disordered medium like biological tissues.

Nonlinear Wavefront Shaping With Nonlocal Metasurfaces
, 2023 We demonstrate wavefront shaping of third-harmonic light generated in nonlocal silicon metasurfaces. The nonlinear geometric phase principle is applied to locally control the phase response of the diffracted third-harmonic light.
