Independent Light Field Manipulation in Diffraction Orders of Metasurface Holography

Abstract Metasurface holograms are novel optical elements with enormous potential because of the charming electromagnetic features, which can manipulate amplitude, phase, polarization state, and other parameters light field via an elaborately designed subwavelength nanostructure array. Metagratings extensively researched for controlling feature in diffraction orders. However, a flexible simple method is yearned realizing independent wavefront manipulation different Here, metasurface holography that reconstruct various information each order demonstrated. The physical model based on Jacobi–Anger expansion iterative optimization, both helicity‐dependent birefringent metasurfaces work compatibly this proposed to achieve arbitrary control 1D 2D Specifically, 18 channels consisting orders states encoded single hologram. approach provides promising versatile beam shaping, holographic display, storage, encryption, etc.
