Metasurface has shown significant advantages in full‐space multifunctional electromagnetic (EM) manipulation due to its strong design capability. Here, a novel transmission–reflection‐integrated metasurface is proposed, which can simultaneously manipulate beam direction and polarization states. Through ingenious design based on the quadratic phase distribution, such a metasurface can dynamically control the beam deflection direction in both transmission and reflection modes by shifting the position of the feeding source. In addition, arbitrarily polarized EM waves can be generated based on the dual‐beam coherent interference method. The above EM functions are experimentally demonstrated at microwave frequencies. The wide‐angle beam steering performance is realized in full space, and its scanning range is beyond ±60°. More remarkably, the deflecting beam with different polarization states can be obtained by simultaneously illuminating the metasurface from the reflection and transmission sides with a specific phase difference. The measured results are in excellent accordance with the numerically simulated results, thus verifying the EM manipulation capability of the metasurface. The proposed design provides a new approach to achieve multifunctional beam manipulation in full space, which holds great promise in integrated optics, radar detection, and wireless communication.

“…The azimuthal index l, corresponding to the orbital angular momentum (OAM) of the optical field, 31,32 has been widely employed in an ocean of physical processes. [33][34][35][36][37][38][39][40][41][42][43][44] Meanwhile, OAM finds applications in both DV [45][46][47][48][49][50][51] and CV [52][53][54][55] quantum systems due to the fact that it can form a high-dimensional Hilbert state space. In sharp contrast to the in-depth study of OAM, the radial index of the radial mode is often overlooked 56 and has only attracted attention in the past few years.…”

Entanglement serves as a fundamental resource for quantum information protocols, and hyperentanglement has received an increasing amount of attention for its high-capacity characteristic. Increasing the scale of hyperentanglement, i.e., the number of modes in a hyperentangled system, is crucial for enhancing its capability in quantum information processing. Here, we demonstrate the generation of large-scale continuous-variable (CV) hyperentanglement in three degrees of freedom (DOFs), including azimuthal and radial indices of Laguerre-Gaussian (LG) modes and frequency. In our experiment, 216 pairs of hyperentangled modes are deterministically generated from the four-wave mixing process in an atomic vapor. In addition, we show that the entanglement between coherent LG superposition modes denoted by both azimuthal and radial quantum numbers can also be generated from this system. Such large-scale CV hyperentanglement in three DOFs presents an efficient scheme to significantly increase the information capacity of the CV system. Our results provide a new platform for studying CV quantum information and open the avenue for constructing high-capacity parallel and multiple-DOF CV quantum information protocols.

“…Recently, the OAM holography proposed by Gu et al has been identified as a vital platform for achieving ultrahigh-capacity holographic multiplexation and high-security encryption without a theoretical limit of helical mode index [9]. After that, complex-amplitude metasurfacebased OAM holography [13], polarization-encrypted OAM metasurface holography [10], modulated OAM holography [14], and high-dimensional nonlinear holography [15,16] have been proposed, which paves the way for optical communication, optical storage, and ultrahigh-security optical encryption.…”

Flexible Image Reconstruction in the Orbital Angular Momentum Holography with Binarized Airy Lens

The orbital angular momentum (OAM) holography has been marked a path to achieving ultrahigh capacity holographic information systems. However, the practical applicability of the OAM holography is limited by the complicated optical setup and unadjustable image intensity and position. Here, a decoding method is proposed by using a binarized phase map derived from an autofocusing Airy beam. By adjusting the parameters of the phase map, the position and intensity distribution of the reconstructed image become flexibly adjustable. In addition, the cross-talk between different image channels can be effectively reduced thanks to the abruptly autofocusing capability of the Airy beams. As a result, the quality and practicability of the OAM holography can be greatly enhanced.
