In 2017, the value of the global market for free space optical communication technology was $229.2 million and it is expected to grow at a compound annual growth rate of 34% during the years 2018-2023. North America and Asia-Pacific are ranked successively the two major global markets. The high demand for fast, flexible wireless technology among all industries including reconnaissance, last and first mile connectivity, backhaul and internet of things are major drivers for the expected growth of free space optics. Moreover, security and high-speed wireless communication, as well as the emerging need for higher flexibility modules, are also key factors that enhance the growth of the global free space optics market. All of these factors are the major forces behind this book's investigation of the performance of FSO under severe conditions and environmental impairment, and how FSO systems can be integrated to enhance the next 5G networks revolution. This book provides an in-depth insight of free space optics already applied in military data security as well as in daily data exchange. This system offers several more advantages compared to other technologies such as low cost, mobility equipment's or security. Moreover, this technology has the potential of becoming an integral and indispensable part of data-processing architectures and telecommunications in the very near future. The book also provides a review of the history of wireless optical telecommunications, together with a synopsis of the application of the principles of electromagnetism in free-space optics. FSO Features and applications are also presented together with an overview of the potential challenges. The environmental impairment itself, which is the key challenge, is put under deep scrutiny. Special attention too is given to the possible mitigation solutions to overcome possible impairments.

Underwater optical wireless communications (UOWC) have gained a considerable interest during the last years as an alternative means for broadband inexpensive submarine communications. UOWC present numerous similarities compared to free space optical (FSO) communications or laser satellite links mainly due to the fact that they employ optical wavelengths to transfer secure information between dedicated point-to-point links. By using suitable wavelengths, high data rates can be attained. Some recent works showed that broadband links can be achieved over moderate ranges. Transmissions of several Mbps have been realized in laboratory experiments by employing a simulated aquatic medium with scattering characteristics similar to oceanic waters. It was also demonstrated that UOWC networks are feasible to operate at high data rates for medium distances up to a hundred meters. However, it is not currently available as an industrial product and mainly test-bed measurements in water test tanks have been reported so far. Therefore, extensive research is expected in the near future, which is necessary in order to further reveal the "hidden" abilities of optical spectrum to transfer broadband signals at higher distances. The present work summarizes the recent advances in channel modeling and system analysis and design in the area of UOWC.

ABSTRACT: Optical wireless communications provide a promising, high bandwidth alternative to radio communications, where high performance links are desired. For large satellites (say, wet mass> 1000kg), laser cross links have been successfully established since 2001 by various space agencies in Europe and Japan. Thus far, the cross-links have been able to achieve data rates in Gbps range for distances greater than 10,000km. Such gains would be monumental improvement for communications in small satellite domain, where the typical communication payload uses radio antenna that achieve an average data rate of 10kbps. The thesis looks at exploring the components of an Intersatellite Laser Link System for large satellites that is responsible for establishing cross links as a means of communication and the feasibility of a similar system to achieve long distance crosslinks for the CubeSat. A brief study of the laser crosslink system of the large satellites is provided. Then, the parameters and requirements of the subsystems are discussed and determined for the CubeSat frame. An analysis of the contribution to the weight of the CubeSat and power consumption requirements are performed with respect to the CubeSat specifications. A link budget analysis was carried out through simulations for the optical system and it was seen that distances upto 200km were achievable with error free communications.
