Machine learning-driven complex models for wavefront shaping through multimode fibers
Jérémy Saucourt, Benjamin Gobé, David Helbert +2
We investigate a method to retrieve full-complex models (Transmission Matrix and Neural Network) of a highly multimode fiber (140 LP modes/polarization) using a straightforward mac…
Experimental phase control of a 100 laser beam array with quasi-reinforcement learning of a neural network in an error reduction loop
Maksym Shpakovych, Geoffrey Maulion, Vincent Kermene +4
An innovative scheme is proposed for the dynamic control of phase in two-dimensional laser beam array. It is based on a simple neural network that predicts the complex field array…
Random scattering and alternating projection optimization for active phase control of a laser beam array
J. Saucourt, P. Armand, V. Kermene +2
A fraction of a laser beam array, whose unknown phase relationships must be set to prescribed values, is launched into a scattering media with random transmission. The resulting ou…
Wavefront shaping for optimized many-mode Kerr beam self-cleaning in graded-index multimode fiber
E. Deliancourt, M. Fabert, A. Tonello +7
We report experimental results, showing that the Kerr beam self-cleaning of many low-order modes in a graded-index multimode fiber can be controlled thanks to optimized wavefront s…
Kerr beam self-cleaning on the mode in graded-index multimode fiber
E. Deliancourt, M. Fabert, A. Tonello +7
We report the experimental observation of Kerr beam self-cleaning in a graded-index multimode fiber, leading to output beam profiles different from a bell shape, close to the $LP_{…
Fast transmission matrix measurement of a multimode fiber with common path reference
Raphael Florentin, Vincent Kermene, AgnÈs Desfarges-berthelemot +1
We report an improved scheme for the measurement of the transmission matrix of multimode waveguides in which the reference field co-propagates with the signal wave. The performance…
