High-speed information processing based on optical microcombs and its performance optimization

In recent decades, photonic technologies offer a solution by enabling ultrahigh speeds for advanced information processing. Among them, microwave photonic signal processors provide high reconfigurability in achieving diverse processing functions. Optical microcombs show appealing advantages by providing numerous wavelength channels from a compact device. This thesis focuses on the realization and performance improvement of microwave photonic signal processors based on optical microcombs. The influence of theoretical and experimental factors is demonstrated and the performance between discrete and integrated systems is compared. This work guides the design of microwave photonic signal processors and opens avenues to new applications.
