4 × 20  Gbit/s mode division multiplexing over free space using vector modes and a q-plate mode (de)multiplexer. [PDF]

open access: yesOptics Letters, 2014
Vector modes are spatial modes that have spatially inhomogeneous states of polarization, such as, radial and azimuthal polarization. In this work, the spatially inhomogeneous states of polarization of vector modes are used to increase the transmission ...
