This article describes recent advances in the generation of millimeter and terahertz waves based on optical heterodyning techniques. For many applications, the main targets are low-phase noise, wide frequency tunability, and high output power. We present 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.
