Control of the temporal and polarization response of a multimode fiber

Wavefront shaping has revolutionized the spatial control of coherent light beams thanks to the use of spatial light modulators (SLM) in disordered systems such as biological tissue, white paint or multimode fibers. Different approaches have been developed to control the propagation of coherent light that has experienced scattering, such as iterative optimization, optical phase conjugation, and the measurement of the optical transmission matrix.
