It has several key features by transferring signals between the optical domain and microwave domain, which leads to the advantages of broad operation bandwidth for generation, processing and distribution of microwave signals and high resolution for optical spectrum measurement. In this paper, we comprehensively review past and current status of MWP in China by introducing the representative works from most of the active MWP research groups. Future prospective is also discussed fi'om the national strategy to key enabling technology that we have developed.展开更多

The grating design methodology is discussed in detail, including practical device fabrication considerations. On-chip implementations of various fun- darnental photonic signal processing units, including Fourier transformers, Hilbert transformers, ultrafast pulse shapers etc., are reviewed. Recent progress on WBGs- based IMWP subsystems, such as true time delay elements, phase shifters, real time frequency identification systems, is also discussed.展开更多
