Abstract: Underwater communication has become one of the most interesting and rapid growing field with its broad areas of water-based applications in military and also in commercial systems. Its communication channels undergo severe attenuation, frequency dispersion, multipath effect and limited power resources which has made it one of the most challenging communications. Of these key challenges, optical and acoustic are the most predominantly compelling underwater communication with complexities for long range and high bandwidth requirement especially power constrained modems. In this paper, integration of both optical and acoustic signals through a single hybrid opto-acoustic modem is proposed for underwater communication. The proposed modem has been simulated for transmission and reception of both optical and acoustic signals. The output signals are verified with respect to the input signal. The proposed design has been simulated and the simulation results prove the success and efficiency of the proposed hybrid modem design. Achieving high bandwidth for long distance transmission with low power consumption and high speed on terrestrial and subsequently in underwater can be carried out as the future work.
