Microwave Photonics

Rapid advance in microwave electronics, photonics, and ultrafast optics has engendered a new field: microwave photonics. Microwave photonics can be defined as the study of photonic devices operating at microwave or millimeterwave and even terahertz frequencies and their use in microwave or photonic systems. From pioneering works during the late 1970s, the field has expanded to produce numerous applications of commercial importance. In this multidisciplinary field at the interface between microwaves, ultrafast optics, and photonic technologies, typical investigations include, for example, measurements of ultrafast signals, high-speed and microwave signal generation, signal processing, and conversion as well as the distribution and transmission of microwave signals via broadband optical links
