Optical Millimeter-Wave and Terahertz Generation: Technologies and Applications reviews recent achievements in the rapidly growing area of photonic continuous-wave, millimeter-wave, and Terahertz Signal generation. This book covers all aspects of the emerging and interdisciplinary field in Microwave Photonics in a compact form and is suitable for use as a reference text and in some cases as a graduate level text. A detailed description of the physical phenomena and state-of-the-art photonic components and technologies will be presented. Owing to the unique characteristics of photonic signal generation, the recent technological achievements have fueled several commercial applications. Some of those, including the Photonic Synthesizer, Radio-over-Fiber Communications, Radar and Radio Astronomy, will be presented.
