The ocean is key to human survival, providing natural resources, most of the global oxygen supply, and economic development through mineral, gas, and oil deposits. Although the sea is primarily considered a silent world, it is abundant with the natural sounds of marine life communication and geological processes. Human activities, especially active sonars, water-polluting, shipping traffic, and underwater vehicles, have significantly affected the aquatic ecosystem and environment. In this talk, recent developments and advances in underwater wireless optical communication will be presented. I will focus my discussion on optoelectronic devices and system challenges facing long-distance, multiple-Gbps underwater wireless optical communication. The future perspective of underwater photonics will also be discussed.
