Automatic Axis-Aligned High-Speed Optical Wireless Communication System Based on Laser Diode

The current RF wireless communication spectrum resources are facing significant scarcity, which hampers their ability to support the requirements for ultra-high data rates and ultra-low latency. Laser Diodes (LD) based optical wireless communication (OWC) has emerged as a potential alternative technology that has garnered considerable attention. OWC utilizes the abundant spectrum of light and offers several advantages, including rich bandwidth, strong security, and high trans-mission rates. In this paper, we propose an automatic axis-aligned high-speed optical wireless communication system based on laser diode. Using the camera and the 2D steering, we demonstrate a mobile real-time OWC system over a distance of 0.8 m and a field angle of ±10°. This system is based on the 10 Gigabit Ethernet protocol and can consistently deliver TCP data transmission at a rate of 9.36 Gbps.
