Spatiotemporal coherent control of light through a multiple scattering medium with the multispectral transmission matrix
Physical review letters, 2016•APS
We report the broadband characterization of the propagation of light through a multiple
scattering medium by means of its multispectral transmission matrix. Using a single spatial
light modulator, our approach enables the full control of both the spatial and spectral
properties of an ultrashort pulse transmitted through the medium. We demonstrate
spatiotemporal focusing of the pulse at any arbitrary position and time with any desired
spectral shape. Our approach opens new perspectives for fundamental studies of light …

We report the broadband characterization of the propagation of light through a multiple scattering medium by means of its multispectral transmission matrix. Using a single spatial light modulator, our approach enables the full control of both the spatial and spectral properties of an ultrashort pulse transmitted through the medium. We demonstrate spatiotemporal focusing of the pulse at any arbitrary position and time with any desired spectral shape. Our approach opens new perspectives for fundamental studies of light-matter interaction in disordered media, and has potential applications in sensing, coherent control, and imaging.
