Summary: Metasurfaces have shown great potential in optical wave manipulation but face challenges in multidimensional manipulation of harmonic waves generated by nonlinear metasurfaces. This study presents an efficient design strategy based on the hydrodynamic model of free electron dynamics, allowing for full complex-amplitude modulation of second harmonic generation. The proposed nonlinear metasurfaces demonstrate spin-selective SHG optical vortices with independent topological charges, opening up new possibilities for nonlinear metasurface applications in optical information and multifunctional integration.

Summary: Efficient and dynamic light manipulation at small scale can be achieved through active optical metasurfaces, which offer compact design and low power consumption. In this study, a dynamically tunable metasurface based on vanadium dioxide is demonstrated, allowing independent control of amplitude and phase without mechanical parts. The nanofabrication of vanadium dioxide enables computationally predicted continuously tuned amplitude and phase modulation. Experimental results show stable intermediate states and repeated modulation without degradation, indicating the potential for reprogrammable optical functionality.

Summary: Unlike other methods that only modify the phase of cross-polarization components, this paper presents a novel concept for multifunctional manipulation of a metasurface through full-phase modulation. This method allows for simultaneous and independent amplitude and phase control of both co- and cross-polarization components of circularly polarized waves. Experimental results at 980nm wavelength demonstrate the feasibility of this complex amplitude control method for circularly polarized light (left or right circularly polarized).

Summary: An elastic metasurface known as gradient folding metasurface (GFMS) is proposed to manipulate the transmission phase and amplitude of flexural waves simultaneously, by varying the gradient index common ratio (CR) between adjacent units. Through the generalized Snell's law, two different cases of wave focusing effect are realized, demonstrating the ability of GFMS to manipulate complete elastic waves through phase and amplitude modulation.

Summary: We propose a composite acousto-optical modulation scheme for wide-band, efficient modulation of CW and pulsed lasers. By adjusting the amplitudes and phases of weakly-driven daughter AOMs, diffraction beyond the Bragg condition can be achieved with exceptional efficiencies. High contrast switching of output orders can be achieved by imaging pairs of AOMs with opposite directions of sound-wave propagation, enabling efficient bidirectional routing of a synchronized mode-locked laser.

Summary: Metasurfaces are artificially designed structures that can efficiently manipulate incident waves, and have recently gained attention in terahertz radiation for their ability to overcome the complexity of bulky optical systems. In this study, we demonstrate different designs of all-silicon terahertz metasurfaces for various applications. By combining geometric and propagation phases, we achieve switchable multiple phase modulation in orthogonal circularly polarized channels. The proposed scheme allows for locked phase modulation profiles and flexible manipulation of wavefronts.
