Abstract

Moiré effect-based metasurfaces consist of two complementary all-dielectric metasurfaces and such Moiré meta-devices are promising for multi-parameter tuning of orbital angular momentum (OAM) beams. Herein, a general sector-separation phase modulation scheme for the Moiré meta-device is proposed to realize reconfigurable OAM beam generation. In this configuration, scalar OAM beam generation and vector OAM beam generation in space are implemented. The transmitted OAM beams allow dynamic and independent adjustment for left-handed circularly polarized (LCP) and right-handed circularly polarized (RCP) incident light. With a simple mutual rotation of the cascaded metasurfaces, both the topological charges of scalar OAM beams and the vector polarization states of vector OAM beams can be dynamically adjusted. The proposed design method of the Moiré meta-device platform provides an effective strategy for flexibly manipulating the properties of OAM beams, suggesting a novel approach for adaptive optical tweezers, structured illumination, and free-space optical communications.

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
