This book provides a comprehensive review and the latest progress of ultraviolet communications. Optical wireless communications employing electromagnetic waves in optical wavebands as information carriers can achieve higher communication bandwidth compared with radio frequency based wireless communication. However, the good directionality of optical waves degrades its non-line-of-sight transmission ability for avoiding obstacles.

The ultraviolet communication employs the ultraviolet light in "solar blind" waveband (200-280 nm) as information carriers. The name "solar blind"...
