1Unscrambling light-automatically undoing strong mixing between modes显示文摘Propagation of light beams through scattering or multimode systems may lead to the randomization of the spatial coherence of the light.Although information is not lost,its recovery requires a coherent interferometric reconstruction of the original signals,which have been scrambled into the modes of the scattering system.Here we show that we can automatically unscramble optical beams that have been arbitrarily mixed in a multimode waveguide,undoing the scattering and mixing between the spatial modes through a mesh of silicon photonics tuneable beam splitters.Transparent light detectors integrated in a photonic chip are used to directly monitor the evolution of each mode along the mesh,allowing sequential tuning and adaptive individual feedback control of each beam splitter.The entire mesh self-configures automatically through a progressive tuning algorithm and resets itself after significantly perturbing the mixing,without turning off the beams.We demonstrate information recovery by the simultaneous unscrambling,sorting and tracking of four mixed modes,with residual cross-talk of−20 dB between the beams.Circuit partitioning assisted by transparent detectors enables scalability to meshes with a higher port count and to a higher number of modes without a proportionate increase in the control complexity.The principle of self-configuring and self-resetting in optical systems should be applicable in a wide range of optical applications.Andrea Annoni Emanuele Guglielmi Marco Carminati Giorgio Ferrari Marco Sampietro David AB Miller Andrea Melloni Francesco Morichetti 2017Light(Science & Applications)2017,6,1:4
