text: Inspired by plant grafting, grafted vortex beams can be formed through grafting
two or more helical phase profiles of optical vortex beams. Recently, grafted
perfect vortex beams (GPVBs) have attracted much attention due to their unique
optical properties and potential applications. However, the current method to
generate and manipulate GPVBs requires a complex and bulky optical system, hindering
further investigation and limiting its practical applications. Here, a compact
metasurface approach for generating and manipulating GPVBs in multiple channels
is proposed and demonstrated, which eliminates the need for such a complex optical
setup. A single metasurface is utilized to realize various superpositions of GPVBs
with different combinations of topological charges in four channels, leading to
asymmetric singularity distributions. The positions of singularities in the superimposed
beam can be further modulated by introducing an initial phase difference in the
metasurface design. The work demonstrates a compact metasurface platform that
performs a sophisticated optical task that is very challenging with conventional
optics, opening opportunities for the investigation and applications of GPVBs
in a wide range of emerging application areas, such as singular optics and quantum
science.
