Wavefront shaping in multimode fibers by transmission matrix engineering
Shachar Resisi, Yehonatan Viernik, Sebastien Popoff +1
One of the greatest challenges in utilizing multimode optical fibers is mode-mixing and inter-modal interference, which scramble the information delivered by the fiber. A common ap…
Distortion matrix concept for deep optical imaging in scattering media
Amaury Badon, Victor Barolle, Kristina Irsch +3
In optical imaging, light propagation is affected by the inhomogeneities of the medium. Sample-induced aberrations and multiple scattering can strongly degrade the image resolution…
A model for full-field optical coherence tomography in scattering media
Ugo Tricoli, Rémi Carminati
We develop a model of full-field optical coherence tomography (FF-OCT) that includes a description of partial temporal and spatial coherence, together with a mean-field scattering…
Influence of the local scattering environment on the localization precision of single particles
Dorian Bouchet, Rémi Carminati, Allard P. Mosk
We study the fundamental limit on the localization precision for a subwavelength scatterer embedded in a strongly scattering environment, using the external degrees of freedom prov…
Multiple scattering enabled superdirectivity from a subwavelength ensemble of resonators
S. Metais, G. Lerosey, F. Lemoult
An ensemble of resonators arranged on a sub-wavelength scale is usually considered as a bulk effective medium, known as a metamaterial, and can offer unusual macroscopic properties…
Optimizing light storage in scattering media with the dwell-time operator
M. Durand, S. M. Popoff, R. Carminati +1
We prove that optimal control of light energy storage in disordered media can be reached by wavefront shaping. For this purpose, we build an operator for dwell-times from the scatt…
