The International Topical Meeting on Microwave Photonics (MWP 2022) is an online event held from 4th October to 6th October 2022. This event is the premier international meeting on microwave photonic devices, systems, and applications. The Conference topics cover all the multi-disciplinary applications of microwave-photonics: the fiber distribution of microwave and millimeter-wave signals, the implementation of new microwave functions (long delays lines, fast spectrum analysis, frequency conversion, low phase-noise oscillators, ultra-fast analog-to-digital converters), and the development of high-speed optical sources, modulators, and detectors with bandwidths extending into the millimeter-wave region.
