Traditional signal and information processing technologies are relatively independent and complicated. Artificial intelligence (AI) technology introduces a processing scheme of signal conversion plus information recognition to improve the level of intelligence in system processing. However, a high intensity of signals and information in future applications demand for more efficient systems and more flexible decision-making capabilities. It was proposed that optoelectronic integration technology was promising to realize the processing of signal and information as a new processing paradigm. Taking the complementary advantages of photonic and electronic technologies in electromagnetic scales, physical advantages, and practical implementations, overall and direct processing of signal and information was achieved and had the potential to integrate deeper levels of intelligence technology. Emerging signal and information processing paradigms enabled by optoelectronic integration were reviewed. The supportive significance of optoelectronic hybrid integration on optoelectronic integration processing technology was demonstrated.
