On-axis structured beams generation via moiré and Mie resonant metallo-dielectric moiré gratings
Abstract Structured beams carrying orbital angular momentum have been generated conventionally using spiral phase plates, fork gratings, and metasurfaces. Spiral phase plates are non-planar, fork gratings do not produce structured beams on the axis, and metasurfaces need subwavelength unit cell leve...
