  • Descrição: Bessel beams have a wide range of applications in optical communications because their non-diffractive properties do not depend on the amplitude and phase distribution in the spatial frequency range. Recently, metasurfaces have been widely utilized as subwavelength materials for light manipulation, including the generation of Bessel beams. However, so far, no reports of metasurfaces generating Bessel beams with polarization rotation function have been published, which has potential applications for information encryption in optical communication. An all-dielectric metasurface based on the Pancharatnam-Berry (PB) phase is proposed to realize the generation of a Bessel beam with polarization rotation function under the incident of linearly polarized (LP) light. Furthermore, we exhibit dual Bessel beams with orthogonal polarization states through the superimposition of two Bessel beam phases onto a metasurface, with different polarization rotation angles and phase gradients. Our final demonstration illustrates Bessel beam arrays with polarization rotation, and this design concept can be extended to more channels and higher-order Bessel beams. The proposed all-dielectric metasurfaces based on polarization rotation function provides a new option for the application of Bessel beams in integrated optical systems and multiplexing. •[Novelty] Proposed an approach to generate Bessel beams with polarization rotation function.•[Results] Generated Bessel beam arrays with orthogonal polarization states.•[Quality] Achieved a close match between the full width at half maximums of the Bessel beams and the theoretical values.•[Applications] Suggested potential applications of the proposed metasurfaces for imaging and information encryption.
