Communications optiques sous-marines : Transmission longue-portée haut-débit et analyse des performances, Underwater Wireless Optical Communications: Long-range High-data-rate Transmission and Performance Analysis

Today we are witnessing a growing need to high-rate data transmission in underwater missions in a wide range of application areas. Within this context, traditional cable- or fiber-based communications imply costly deployments with very limited flexibility, andthe conventional acoustic communications offer very low operational performance. Recently, with the development of small and low-cost optoelectronic components and devices, it has become feasible to realize small and compact wireless optical communication transceivers providing unprecedentedly high transmission rates and energy efficiency. However, there still remain several shortcomings of this technology, in particular to attain high data rates over relatively long communication ranges.In order to overcome some of these limitations, this PhD thesis considers the use of advanced optoelectronic components and signal processing techniques in order to improve the performance of underwater wireless optical communication (UWOC) links.
