“…Such an important property makes it promising to find many applications in advanced EM manipulations and multi-domain signal processing. The optoelectronic metasurface can be used to realize optically driven and optical-sensing microwave metasurfaces and devices that are capable of achieving wireless-control functions, such as cloaking, beamforming, and nonlinear generation. − Compared with the traditional electrically controlled metasurfaces, the optically driven metasurfaces enable remote control of microwaves by spatial light, which can effectively mitigate the complexity of the bias network and the DC-EM crosstalk. Moreover, the optically driven metasurface offers an efficient interface to link light and microwave in free space, providing a low-profile platform to realize the wave-based direct conversions of optical and microwave signals, which is fundamentally important to the optoelectronic hybrid wireless communications, quantum networks, and relevant applications.…”

Photon-electron interactions are essential for many areas such as energy conversion, signal processing, and emerging quantum science. However, the current demonstrations are typically targeted to fiber and on-chip applications and lack of study in wave space. Here, we introduce a concept of optoelectronic metasurface that is capable of realizing direct and efficient optical–microwave interactions in free space. The optoelectronic metasurface is realized via a hybrid integration of microwave resonant meta-structures with a photoresponsive material. As a proof of concept, we construct an ultrathin optoelectronic metasurface using photodiodes that is bias free, which is modeled and analyzed theoretically by using the light-driven electronic excitation principle and microwave network theory. The incident laser and microwave from the free space will interact with the photodiode-based metasurface simultaneously and generate strong laser–microwave coupling, where the phase of output microwave depends on the input laser intensity. We experimentally verify that the reflected microwave phase of the optoelectronic metasurface decreases as the incident laser power becomes large, providing a distinct strategy to control the vector fields by the power intensity. Our results offer fundamentally new understanding of the metasurface capabilities and the wave–matter interactions in hybrid materials.

Programmable metamaterials and metasurfaces have gained great interest due to real‐time electromagnetic control and digital information processing capabilities. Different from traditional electrically‐controlled programmable metasurfaces, recently, light‐controlled programmable metasurfaces have been presented, on which the microwaves can be manipulated and modulated wirelessly in the space domain or time domain by incident light. More importantly, such the metasurface platform offers an efficient interface to link directly light and microwave signals, showing huge potential to develop wave‐based optoelectronic hybrid devices and relevant applications. Here, we review some of these recent developments, focusing particularly on the mechanisms of light‐controlled programmable metasurfaces and their fascinating functions from remote microwave control to hybrid signal processing. We survey related implementation methods based on the hybrid integrations of microwave digital metasurfaces and different photoresponsive components including photodiodes, photoresistors, infrared modules, and light sensors, as well as discuss their unique advantages. In the summary, the perspective on the challenges and future directions of light‐controlled programmable metasurfaces are presented.

Currently, light-transmitting, energy-saving, and electromagnetic shielding materials are essential for reducing indoor energy consumption and improving the electromagnetic environment. Here, we developed a cellulose composite with excellent optical transmittance that retained the natural shape and fiber structure of bamboo. The modified whole bamboo possessed an impressive optical transmittance of approximately 60% at 6.23 mm, illuminance of 1000 luminance (lux), water absorption stability (mass change rate less than 4%), longitudinal tensile strength (46.40 MPa), and surface properties (80.2 HD). These were attributed to not only the retention of the natural circular hollow structure of the bamboo rod on the macro, but also the complete bamboo fiber skeleton template impregnated with UV resin on the micro. Moreover, a multilayered device consisting of translucent whole bamboo, transparent bamboo sheets, and electromagnetic shielding film exhibited remarkable heat insulation and heat preservation performance as well as an electromagnetic shielding performance of 46.3 dB. The impressive optical transmittance, mechanical properties, thermal performance, and electromagnetic shielding abilities combined with the renewable and sustainable nature, as well as the fast and efficient manufacturing process, make this bamboo composite material suitable for effective application in transparent, energy-saving, and electromagnetic shielding buildings.
