Speech Title: Research Progress in Underwater Optical Wireless Communications Abstract：The recent breakthrough in semiconductor light sources and detection technology brings new opportunities for mobile wireless communication and networking in marine environments. Ocean optical wireless communication uses light waves as wireless information carriers, which not only compensates for the shortcomings of bandwidth and transmission delay in underwater acoustic communication, but also offers more flexibility than fiber optic deployment. It can complement the advantages of underwater acoustic and fiber optic, and build a multimodal communication network for the ocean. However, it still faces difficulties in extending to sub-kilometer transmission, such as dynamic interference from water components, unstable posture of transmitting and receiving terminals, and weak signal reception. This talk focuses on marine optical wireless communication and multiple access technology. It also covers the development of lightweight and opto-mechatronic integrated prototypes to support marine communication networks and serve applications such as marine entertainment and tourism, mineral exploration, robot operations, and security. |

Speech Title: Near-ground High-Speed Atmospheric Laser Communication Technology and Experimental Research Abstract: Wireless laser communication, with its advantages of large communication capacity, high transmission rate, strong anti-interference ability, light weight, small size and low power consumption, well meets the urgent requirements of high-speed information transmission between space information nodes, and it has broad application prospects and important application value in the integrated information network of land, sea, air and space. Turbulent channels will cause beam diffusion, light intensity flicker, beam drift, etc., thereby resulting in phase distortion, intensity jitter and deterioration of signal-to-noise ratio of the detection signal of the optical terminal equipment. Turbulent channels will seriously affect the communication quality and even lead to communication interruption. To address the above-mentioned challenges, technical breakthroughs were made from the perspectives of non-diffracted beam control, mode amplification and diversity, multi-format and multi-aperture, and adaptive receiving gain. The relevant technical hardware design and development were completed, and a series of indoor and outdoor laser communication experiments were conducted to verify the technical feasibility. The related research results will provide certain references for the future development of space laser communication.
