摘　　要：介绍了非线性光信号处理的基本概念、发展历史和主要物理过程。从光信号处理的角度分析了各种集成材料平台或结构设计在非线性增强中的优势和不足,讨论了非线性光信号处理器件在光通信、光计算和量子信息领域的典型应用,最后对非线性光信号处理集成器件的未来发展趋势进行了展望。Significance In recent years,global big data and network traffic have experienced explosive growth,and signal processing faces significant challenges in capacity and energy consumption.Currently,more than 90%of data information is transmitted via optical waves.As long as information processing is conducted using electronic devices,optical-electrical-optical(O-E-O)conversion is required.Compared to the processing speed of electronic devices,the bandwidth of optical signal transmission is significantly large.The signal should be demultiplexed into multiple low-rate signals,which can then be processed in the electrical domain to facilitate optical signal processing.However,demultiplexing and subsequent processing will increase the required number of O-E-O conversion devices,resulting in higher system complexity,costs,and energy consumption.On the other hand,optical nonlinear effects feature ultrafast response,large bandwidth,and parallelism,which can directly process high-speed optical signals.Nonlinear optical signal processing(NOSP)is the process of employing optical nonlinear effects to process information.If efficient enough,NOSP has the potential to significantly reduce the cost and power consumption of network information exchange and processing.Unfortunately,NOSP usually requires high-power lasers since photons are bosons and the interactions between photons are usually weak.The interaction between light and matter should be enhanced to reduce power consumption.In recent years,the development of semiconductor integration technology has promoted the development of photonic devices toward integration.Photonic integrated devices feature low cost,low power consumption,light weight,high stability,and small size,which are beneficial for realizing more complex functional devices.Additionally,photonic integrated devices can localize the optical field in a very small area,greatly enhancing the interaction between light and matter.Meanwhile,integrated material platforms with high refractive indices have high nonlinear
