Polarization: Optical Polarization Encoding Using Graphene‐Loaded Plasmonic Metasurfaces (Advanced Optical Materials 1/2016)

S. Chen, J. Tian, and co-workers propose a graphene-loaded metadevice which can dynamically modulate the polarization state of light over a wide range. On page 91, the polarization state of the reflected light can be modulated to be right circularly polarized, left circularly polarized, and linearly polarized by switching the gate voltage between three different values. Based on this polarization-control feature, the metadevice can be employed for realizing polarization encoding and polarization-division multiplexing techniques based on circular orthogonal polarization.
