Summary: Metasurfaces with orthogonal nano-slit pairs arranged on spirals are proposed to generate vector beams of Bell-like states and slanted polarizations. The design is based on the theoretically derived parameter condition for manipulation of the two vector vortex modes, satisfied by matching the rotation order m, the spiral order n, and incident polarization helicity sigma. Linear polarization states of the vector beams are controlled by the initial orientation angle of slit pairs.

Summary: In this study, a new method for achieving robust asymmetric generation of acoustic vortex field through dual-layer metasurfaces is introduced. This is achieved by controlling the intrinsic topologic charges and the parity of geometry design. The underlying physics is contributed to the one-way process of orbital angular momentum transition ensured by the broken spatial symmetry and the external topologic charge from the vortex diffraction. The novel phenomenon is experimentally demonstrated, providing new routes to manipulate the asymmetric response of vortex fields and potential applications in passive OAM-based diodes.

Summary: Space-time quantum metasurfaces provide a compact platform for manipulating quantum light, allowing continuous tuning of coherent light-matter interactions in space and time. They enable arbitrary control of the spectral, spatial, and spin properties of nonclassical light, leading to tailored entanglement of single photon degrees of freedom and generation of steered and vortex photon pairs. These metasurfaces have the potential to enable novel photonic functionalities, such as encoding quantum information into high-dimensional color qudits and generating reconfigurable hyperentanglement for high-capacity quantum communications.

Summary: The rapid development of artificial material designing and nanoprocessing technology has greatly facilitated the growth of novel planar optical devices. Traditional optical phase gradient devices face limitations in scaling down size, so new strategies are needed. In this study, we develop a series of novel compact planar devices using the superpositionable, polarization-dependent properties of the Pancharatnam-Berry phase. Our compact devices, made of well-designed dielectric glass plates, offer a new and simple solution to transmission loss in a cascade system of phase gradient devices.

Summary: By utilizing the fundamental electromagnetic properties of metasurfaces, we have developed a platform for classifying reciprocal bianisotropic metasurfaces and determining their isotropic, anisotropic, bi-isotropic, and bianisotropic properties. We have provided experimental guidelines for identifying each class using macroscopic scattering parameters, such as reflection and transmission coefficients, under plane wave illumination with linear and/or circular polarization. We have also clarified common confusions in the classification of anisotropic and chiral metasurfaces based on circular dichroism measurements.
