Abstract
Underwater Optical Wireless Communication (UOWC) has gained significant attraction in many underwater activities because of its high bandwidth as compared to radio frequency and acoustic technologies. Underwater Optical Wireless Communication (UOWC) has high stature in underwater observation, exploration and monitoring applications. However, due to complex nature of ocean water, several practical challenges exist in deployment of UOWC links. Qualitative and effective research has been carried out in UOWCs from last few decades. Ambition behind this research systematic study is to provide a comprehensive survey on latest research in UOWCs. Herein, we provide a brief discussion on major research challenges, limitations and development in UOWCs. We provide a periodical review on UOWC issues and potential challenges highlighted in previous studies. In this paper, we have also investigated research methods to gain attention of research fraternity towards future technologies and challenges on the basis of existing approaches. Thus, it is our foremost requirement to provide state-of-the-art analysis of existing UOWCs. Significant deliberation has been provided with recent bibliography.

Summary
An extensive research has been carried out on free space optical wireless communications in different aspects and nowadays Underwater Optical Wireless Communication (UOWC) is generating considerable attention among recent researchers. UOWC is an emerging technology for premier research in underwater environment. It is a fusion of optical and wireless technologies having intelligent computing, smart sensing and communication abilities. The unpredictable condition of ocean environment generates these serious challenges and issues in designing and deployment of UOWC links. We have briefly discussed the feasible countermeasures to tackle these challenges in existing UOWC mechanism. It shows that different underwater platforms such as submarine, sensors, ships and divers are connected through light beams. An extensive research is being carried out to develop a complementary technology which can allow broadband underwater communications such as real-time video transmissions, tele-operation of AUVs and remote monitoring of underwater stations [4]. We have included modulation schemes, channel coding, UOWC challenges and OWC revolution in www.ijacsa.thesai.org
