在基于光的自由空间通信平台中，中红外（MIR）光在生物医学工程、环境监测和遥感系统中具有重要应用。使用两个相同的设备将MIR产生和接收集成在网络中对于MIR通信的小型化和简化至关重要。然而，传统的MIR发射器和接收器由于低性能的固有限制而不是双向的，并且通常需要低温冷却。在这里，我们证明了宏观石墨烯纤维（GF）组装从弱耦合石墨烯层允许室温MIR检测和发射兆赫调制频率由于在毫米长度的光热电效应的持久性和快速调制灰体辐射的能力。基于GF的双重功能，我们建立了一个系统，进行双向数据传输的两个相同的GF之间的模式切换。我们系统的室温操作和在工业纺织品规模上生产GF的潜力为简化和可穿戴的光通信提供了机会。在这里，作者设计了宏观多层石墨烯纤维，在中红外范围内具有发光和检测双重功能，提供兆赫调制频率和双向数据传输操作。
Among light-based free-space communication platforms, mid-infrared (MIR) light pertains to important applications in biomedical engineering, environmental monitoring, and remote sensing systems. Integrating MIR generation and reception in a network using two identical devices is vital for the miniaturization and simplification of MIR communications. However, conventional MIR emitters and receivers are not bidirectional due to intrinsic limitations of low performance and often require cryogenic cooling. Here, we demonstrate that macroscopic graphene fibres (GFs) assembled from weakly-coupled graphene layers allow room-temperature MIR detection and emission with megahertz modulation frequencies due to the persistence of photo-thermoelectric effect in millimeter-length and the ability to rapidly modulate gray-body radiation. Based on the dual-functionality of GFs, we set up a system that conducts bidirectional data transmission by switching modes between two identical GFs. The room-temperature operation of our systems and the potential to produce GFs on industrial textile-scale offer opportunities for simplified and wearable optical communications. Here, the authors design macroscopic multi-layered graphene fibres with light-emission and -detection dual functionality in the mid-infrared range, offering megahertz modulation frequencies and bidirectional data transmission operation.
