Laser Based Underwater Communication

Abstract: To revolutionise under water communication system  with the use of narrow beam LASER as the wireless  medium for transmission and reception of data. To provide a very high data rate of (1 gbps - 256 gbps)  which is far greater than the data rate provided by  acoustic communication(1kbps-50kbps). We also discuss the advantages of operating with single mode laser devices and matched filtering at the receiver in the context of applications with significant solar background.

Keywords: Visible lasers, frequency modulation, optical communication, oceanic optics, wavelength filtering devices.
