Reconfigurable orbital-angular-momentum manipulation and switching of polarization-multiplexed 100-Gbit/s QPSK data channels

We demonstrate a scheme that can arbitrarily manipulate the orbital-angular-momentum (OAM) and the polarization of each data channel in an OAM- and polarization-multiplexed communication system. A manipulation-induced power penalty of <; 1dB is observed when 100 Gbit/s Quadrature-phase-shift-keying data is carried on each channel.
