Photonic Devices for Ultra-Broadband Wireless Links, Sensing and Measurement Systems

We review recent progress in photonic devices for millimeter-wave (MMW) wireless links, imaging, and sensing. O/E conversion of optical signals that are modulated at high-frequency is suitable for generating high frequency radio waves with wide frequency tunability. Electro-optic (EO) measurements enable a wide bandwidth and low invasiveness. This paper highlights a MMW wireless links, MMW imaging, sensing, and measurements, and describes key devices, including photonic MMW sources, high-speed photonic transmitters, and EO sensors.
