The high frequency of optical radiation permits high data rate communications in the megahertz (MHz) regime. To the best of our knowledge, no unguided, underwater high data rate communications system has been reported. In this research, we investigate the feasibility of a short range, high data rate underwater laser communications system. The present study considers two independent systems that are separated by several attenuation lengths with regard to signal acquisition, communications channel lock, and information transfer. System self-alignment of the transmitter onto the receiver is demonstrated in a small laboratory water tank. Successful transmission of light modulated at MHz rates is demonstrated in a pool over an extended water path.
