Signal processing is always the heart of the overall information technology and industry, providing enabling solu- tions for the processing, understanding, learning, retrieval, mining, and extraction of information from different sig- nals. Regarding the all-optical signal processing, it dates back to the 1980s when the electronic bottleneck was considered as a big obstacle to the bandwidth and capacity of optical communications. Fortunately, all-optical signal processing provides intrinsic wide instantaneous bandwidth and large time-bandwidth product (TBP),
