Free-space communication with over 100 spatial modes

By combining both the azimuthal and radial components of Laguerre-Gaussian modes with wavelength division multiplexing, we generated >100 information channels. We implemented a laboratory free-space link using 35 Laguerre-Gaussian modes and three wavelengths.
