Photonic generation of millimeter and terahertz waves and its applications

This paper describes recent advances in the generation of millimeter and terahertz waves based on photonic techniques, which provides low-phase noise, wide frequency tunability, and high output power. Basic component technologies such as an optical frequency comb generator, photonic light-wave circuits for signal processing, and antenna-integrated photodiode modules, and their applications to high-performance measurement and communications are presented.
