This generator produces optical vortex arrays efficiently, indicating potential for optical manipulation and communications.
We report a focused optical vortex array (FOVA) generator prepared by printing a Dammann spiral zone plate on the composite fiber facet using femtosecond laser two-photon polymerization. The generation of FOVA is verified by simulation and experiment. The all fiber generator of FOVA exhibits high flexibility and compactness, making it a suitable candidate for applications in fields such as optical manipulation and optical communications.
