Microwave photonics is a multidisciplinary field that encompasses optical, microwave, and electrical engineering. The microwave photonics field must therefore span frequencies of below 1 kHz in the radio‐frequency (RF) domain to frequencies of hundreds of terahertz associated with the optical domain. The use of RF for telegraph communications in the early to mid‐1800s gave birth to the need for radio engineers. Although modern RF systems increasingly use digital signal processing (DSP), analog fiber optic links offer the radio engineer significant and useful tools in the design of these systems. The RF photonics technology that exists would not be possible if it were not for the use of fiber optics in digital communication systems. The use of optical fiber to transport digital bits of information across the globe has fundamentally changed the way the world communicates. A fiber optic solution affords improved phase stability over all‐electronic approaches.
