Abstract

Over the last decade, wavefront shaping techniques with spatial light modulators have enabled the control of coherent light through disordered systems, like biological tissues or multimode fibre that has suffered from scattering or mode mixing. Beyond spatial focusing of light on a single speckle grain, these techniques have been extended to the control of broadband light. Spatio-temporal focusing has been achieved, which corresponds to compensation for the pulse broadening in a single speckle grain [1]. The temporal control of light in all the spatial positions, including the full polarization control, has however not been achieved.
