dc.description.abstract Current communication systems make use of polarization and wavelength multiplexing to increase transmission rates. To offer a further improvement, Orbital Angular Momentum (OAM) modes (or Laguerre-Gaussian modes) provide an infinite dimensional space. In this work, Laguerre-Gaussian modes are multiplexed and de-multiplexed by means of two Spatial Light Modulators (SLMs), making use of both their azimuthal and radial degrees of freedom. Due to the orthogonality of these modes, a modal decomposition technique is employed to detect the transmitted modes. Here we demonstrate this concept by transmitting an image over a 150 meter free-space link. The free-space link is also characterized in terms of its optical turbulence. en_US
