Query: Custom-tailored spatial mode sorting by controlled random scattering   The need to increase data transfer rates constitutes a key challenge in
modern information-driven societies. Taking advantage of the transverse spatial
modes of light to encode more information is a promising avenue for both
classical and quantum photonics. However, to ease access to the encoded
information, it is essential to be able to sort spatial modes into different
output channels. Here, we introduce a novel way to customize the sorting of
arbitrary spatial light modes. Our method relies on the high degree of control
over random scattering processes by preshaping of the phase structure of the
incident light. We demonstrate experimentally that various sets of modes,
irrespective of their specific modal structure, can be transformed to any
output channel arrangement. Thus, our method enables full access to all of the
information encoded in the transverse structure of the field, for example,
azimuthal and radial modes. We also demonstrate that coherence is retained in
this complex mode transformation, which opens up applications in quantum and
classical information science.
