Underwater Video Communications

Underwater Video

The specific scientific objectives of the project are as follows. First, to characterize the statistics of fading in UOWC channels and analyze the corresponding system performance. Second, to develop a novel high speed GaN-based laser diode that can be directly modulated to >2.5GHz, and produces 0.5W optical power, low beam divergence at a single frequency that match the highest transmission wavelength of red sea water. Third, to develop a low-cost, energy-efficient transceiver for UOWC systems supporting high data rate (i.e. up to 1 Gbps and wider transmission coverage up to 1 kilometer). Finally, to build a prototype and perform system testing and debugging to ensure smooth reliable operations in the Red Sea. This project started on July 2014 and is being funded by KAUST OCRF in collaboration with the Red Sea center for three years. We have already completed phase one of the project, which consists of testbed construction along with the measurements.
