Broadband microwave signal generation and processing based on optical domain controlling

Microwave photonic technology has advantages of large bandwidth, high frequency, flexible reconfigurability and immunity to electromagnetic interference, which is widely used for the generation and processing of microwave signals. In this paper, we review our recent works about microwave signal generation and processing based on optical domain controlling, including photonic generation of multi-band and multi-format microwave waveforms, and microwave photonic temperature interrogation based on temperature-to-time mapping. The proposed works have great potential in practical applications, such as radar, measurement as well as sensing.
