The vanishing distance: a practical range boundary for dynamic wavefront shaping
Hugo Lassiette, Léa Testé, Léa Krafft +6
Wavefront shaping (WFS) is a powerful modern method to control light propagation through scattering media, with applications ranging from biomedical imaging via cryptography to fre…
Nanosecond wavefront shaping to focus through agitated turbid media
Hugo Lassiette, Léa Krafft, Geoffrey Maulion +9
Multiple scattering rapidly scrambles optical fields in fog, snow and turbid water, causing op- timized wavefront corrections to become obsolete on microsecond timescales. Although…
A practical guide to Digital Micro-mirror Devices (DMDs) for wavefront shaping
Sébastien M. Popoff, Louis Malosse, Rodrigo Gutiérrez-Cuevas +5
Digital micromirror devices have gained popularity in wavefront shaping, offering a high frame rate alternative to liquid crystal spatial light modulators. They are relatively inex…
Open transmission channels in multimode fiber cavities with random mode mixing
Guy Pelc, Shay Guterman, Rodrigo Gutiérrez-Cuevas +3
The transport of light in disordered media is governed by open transmission channels, which enable nearly complete transmission of the incident power, despite low average transmiss…
Tutorial: How to build and control an all-fiber wavefront modulator using mechanical perturbations
Ronen Shekel, Kfir Sulimany, Shachar Resisi +4
Multimode optical fibers support the dense, low-loss transmission of many spatial modes, making them attractive for technologies such as communications and imaging. However, inform…
Characterization and Exploitation of the Rotational Memory Effect in Multimode Fibers
Rodrigo Gutiérrez-Cuevas, Arthur Goetschy, Yaron Bromberg +10
In an ideal perfectly straight multimode fiber with a circular-core, the symmetry ensures that rotating the input wavefront leads to a corresponding rotation of the output wavefron…
