Summary: In this work, dynamically switchable metasurfaces based on vanadium dioxide are presented, achieving state switching of reflected wavefront for circularly polarized wave in the terahertz band. Phase modulation is achieved by rotating the vanadium dioxide strip, and the phase transition between metallic and insulating states enables the design of applications such as gradient metasurfaces, vortex beam generators, and reflective lenses with switchable focusing function.

Summary: This paper proposes a high-efficiency reflective-type coding metasurface that can manipulate the scattering pattern of terahertz waves and implement novel functionalities using the Pancharatnam-Berry (PB) phase concept. By optimizing coding sequences, the designed metasurfaces demonstrate strong control over reflected terahertz waves.

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: 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: This letter presents a bifunctional full-space metasurface (FS-MS) capable of generating reflective multiple vortex beams and focusing transmissive electromagnetic waves within different frequency bands. The generation of vortex beams is achieved by rotating the orientation angle of an I-shaped patch based on the Pancharatnam-Berry (PB) phase. A metallic square loop frequency selective surface (FSS) is used to support the PB unit, which allows the generation of reflective vortex beams at a higher frequency band. At a lower frequency band, the incident waves can pass through the FSS-backed PB unit and be focused by a three-layer composite unit. The proposed FS-MS can function as a multiple OAM beams generator and a focusing lens simultaneously.

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: A four-orbital angular momentum (OAM) modes converter has been implemented and characterized with the cascade of an OAM demultiplexer and an OAM multiplexer. The OAM multiplexer is based on four tunable OAM emitters allowing the selection of the emitted OAM mode order by thermal tuning. The completely passive OAM demultiplexer consists of the cascade of two patterned refractive elements followed by a lens and can work independently of the input signal's polarization.
