Light fields in complex media: Mesoscopic scattering meets wave control
Stefan Rotter,Sylvain Gigan +1 more
TL;DR: In this article, a review summarizes how insights from mesoscopic scattering theory have direct relevance for optical wave control experiments and vice versa, and the results are expected to have an impact on a number of fields ranging from biomedical imaging to nanophotonics, quantum information, and communication technology.

Spatial beam self-cleaning in multimode fibres
Katarzyna Krupa,Katarzyna Krupa,Alessandro Tonello,Badr Mohamed Ibrahim Shalaby,Badr Mohamed Ibrahim Shalaby,Marc Fabert,Alain Barthélémy,Guy Millot,Stefan Wabnitz,Stefan Wabnitz,Vincent Couderc +10 more
TL;DR: In this article, the authors show that the Kerr effect in a graded-index (GRIN) MMF is the driving mechanism that overcomes speckle distortions, and leads to a counterintuitive effect that results in a spatially clean output beam robust against fibre bending.

Self-organized instability in graded-index multimode fibres
Logan G. Wright,Zhanwei Liu,Daniel A. Nolan,Ming-Jun Li,Demetrios N. Christodoulides,Frank W. Wise +5 more
TL;DR: In this article, the authors study a regime in which all these elements are integral and provide evidence that the origin of these processes is a universal unstable attractor in graded-index multimode fibres.
Journal ArticleDOI
Multimode optical fiber transmission with a deep learning network.
TL;DR: RahRahmani et al. as mentioned in this paper showed that CNN can learn the nonlinear relationship between the amplitude of the speckle pattern (phase information lost) obtained at the output of the fiber and the phase or the amplitude at the input of the fibre.

A practical algorithm for the determination of phase from image and diffraction plane pictures
TL;DR: In this article, an algorithm is presented for the rapid solution of the phase of the complete wave function whose intensity in the diffraction and imaging planes of an imaging system are known.

Focusing coherent light through opaque strongly scattering media
Ivo M. Vellekoop,Allard Mosk +1 more
TL;DR: Focusing of coherent light through opaque scattering materials by control of the incident wavefront with a brightness up to a factor of 1000 higher than the brightness of the normal diffuse transmission is reported.
Journal ArticleDOI
Weakly guiding fibers.
TL;DR: Simple formulas and functions for the fiber parameters are presented as a help for practical design work that considers the propagation constant, mode delay, the cladding field depth, and the power distribution in the fiber cross section.

Measuring the transmission matrix in optics: an approach to the study and control of light propagation in disordered media.
Sebastien M. Popoff,Geoffroy Lerosey,Rémi Carminati,Mathias Fink,A. C. Boccara,Sylvain Gigan +5 more
TL;DR: The transmission matrix of a thick random scattering sample is determined and it is shown that this matrix exhibits statistical properties in good agreement with random matrix theory and allows light focusing and imaging through the random medium.
