Optical Communications for ASW and MIW Applications

DOD / NAVY
To get around the obvious limitations of current state of the art underwater acoustic communications systems, it is important to consider the use of optical communications in the next generation of underwater communications systems. An underwater optical communications network has various advantages, such as high data rate capability, clear communication in acoustically noisy environments, and the ability to maintain covertness. SA Photonics is proposing a solution to address the need for increased fleet and port security in noisy and littoral harbor waters. In this proposal, SA Photonics proposes the use of an underwater multifunction optical system that combines both imaging and optical communications functions by use of our innovative Phase-locked intensity modulated blue-green source and heterodyne receiver technology. Combining these two technologies and leveraging our expertise in Fast Scanning Mirror technology, optical communications protocols, electro-optic modulation techniques, and Digital Signal Processing will provide an effective hybrid underwater optical communication solution. The SA Photonics optical communication approach will provide a system with advanced underwater communication, FAMIS imaging (LIDAR-RADAR), tracking, and surveillance capabilities. The data rate adaptive and power adaptive link along with the small size of this fiber-based solution make this a perfect fit for an undersea distributed network.
