Optical neuromimetic systems can simulate neuromimetic algorithms at speeds of several to one billion times faster than biological ones, outperform electrical neuromorphic hardware systems and are capable of performing more complex computational tasks than traditional optics. Optical neuromorphology calculation explores the adaptability, robustness and speediness of ultrafast optical pulse signals, and avoids the problems of traditional digital light chip integration and noise accumulation in analog light calculation. This paper reports the development of photon neuromimetic information processing and introduces the key theories and techniques of photon neuromimetry from the aspects of photon neurons, optical pulse learning algorithms and the integrated optical neuromorphic network framework. The necessity and existing problems of light neuromorphism calculation are expounded, and its potential application prospects are prospected.
