High-base vector beam encoding/decoding for visible-light communications

Abstract: Polarization is a basic property of light. Different from well-known linear, circular, and elliptical polarizations, which are spatially homogeneous, a vector light beam with spatially variant polarization states has received increasing interest for its expanded functionalities. In this Letter, we present a visible-light communication link exploiting high-base vector beam encoding/decoding. Using a single phase-only spatial light modulator, we generate 16 states of vector beams representing hexadecimal numbers… Show more

“…In principle, l can take arbitrary integer number ranging from −∞ to +∞, and OAM modes with different l values are intrinsic orthogonal. Similar to other mode bases in free space or fibre 3335 , OAM modes are another mode basis with which to represent spatial modes. One can use different mode bases for MDM, and so does OAM modes.…”

“…Since the orbital angular momentum associated with the spiral phase of Laguerre‐Gaussian (LG) beams was demonstrated by Allen et al. in 1992, the light fields that contain phase singularities have been extensively investigated and applied to various realms, including optical imaging, particle manipulation, optical information storage, communication, and so on . Recently, a new family of null solutions to Maxwell's equations in 3D, whose vorticity line (connected phase singularities in 3D space) is connected as isolated loop in the forms of knots and links, has been reported and attracted increasing interest, because of its nontrivial spatial feature.…”

“…Both VB and CVB has attracted much attention due to their unique optical properties and have shown exciting perspective in various applications ranging from optical manipulation to imaging and optical communication etc 313 . Especially for optical communication, it is believed that the phase singularity and vector singularity can be used as new multiplexing/modulation dimension to improve the communication capacity and capacity density 7, 8, 1113 . More interestingly, the spatially inhomogeneous polarization and helical phase wavefront can coexist in one light beam and thus form cylindrical vector vortex (CVV) beam, which can provide additional degrees of freedom for beam manipulation 14, 15 .…”
