1. A plasmonic system, comprising:
at least one polarizer, configured to provide at least one linearly polarized broadband light beam;
an anisotropic plasmonic metasurface (APM) assembly having a plurality of nanoantennae (unit cells) each having a predetermined orientation with respect to a global axis representing encoded digital data, the APM assembly configured to receive the at least one linearly polarized broadband light beam and by applying localized surface plasmon resonance, reflect the light with selectable wavelengths associated with the predetermined orientations of the nanoantennae;
at least one analyzer, configured to receive the reflected light with selectable wavelength, wherein the relative angles between each of the at least one analyzers and each of the at least one polarizers with respect to the global axis are selectable with respect to the orientation of the nanoantennae, thereby allowing decoding of encoded digital data.
