Abstract

The implementation of an advanced light receiver is imperative for the widespread application of visible light communication. However, the integration of multifunctional and high-performance visible light receivers is still limited by device structure and system complexity. Herein, a graphene-readout silicon-based microtube photodetector is proposed as the receiver for omnidirectional Mbps-level visible light communication. The integration of graphene-semiconductor material systems simultaneously ensures the effective absorption of incident light and rapid readout of photogenerated carriers, and the device exhibits an ultrafast response speed of 75 ns and high responsivity of 6803 A W⁻¹. In addition, the microtube photodetector realizes the omnidirectional light-trapping and enhanced polarization photodetection. As the receiving end of the visible light communication system, the microtube photodetector achieves a data rate of up to 778 Mbps, a field of view of 140°, and the encrypted visible light communication of polarized light, providing a new possibility for the future development of the internet of things and information security.

用于加密可见光通信的石墨烯读出硅基微管光电探测器

要广泛应用可见光通信，就必须采用先进的光接收器。然而，多功能、高性能可见光接收器的集成仍然受到器件结构和系统复杂性的限制。本文提出了一种石墨烯读出硅基微管光电探测器，作为全向 Mbps 级可见光通信的接收器。石墨烯-半导体材料系统的集成同时确保了入射光的有效吸收和光生载流子的快速读出，该器件具有 75 ns 的超快响应速度和 6803 A W-1 的高响应率。此外，微管光电探测器还实现了全向光捕获和增强偏振光电探测。作为可见光通信系统的接收端，微管光电探测器实现了高达 778 Mbps 的数据传输速率、140° 的视场角以及偏振光加密可见光通信，为未来物联网的发展和信息安全提供了新的可能。
