Experimental Demonstration Of A Feedback-Assisted Orbital Angular Momentum-Based Underwater Wireless Optical Link Across The Underwater-To-Air Interface

We experimentally demonstrate a feedback-assisted 1.08 Gb/s orbital angular momentum (OAM)-based underwater-to-air wireless optical link with a floating mirror for beam steering. The experimental results show favorable performance of the proposed feedback scheme in the present of the change of water level.
