Spin-controlled generation of a complete polarization set with randomly interleaved plasmonic metasurfaces

https://phys.org/news/2024-08-generation-polarization-randomly-interleaved-plasmonic.html

"full set polarization states (left/ right-handed circularly polarized light, linearly polarized light in different orientations) switchable across multiple channels, integrated into single optical metasurface... reflective gold-silica-gold plasmonic metasurface, 6 randomly interleaved metasurface regions each outputting/ collecting different polarization states at distinct reflection angles simultaneously... integrating nanoscale plates bearing different rotational angles for simultaneous output... imaging, sensing, communication"
