光学信号处理将光学和信号处理的各个领域-即非线性器件和过程、模拟和数字信号以及高级数据调制格式-结合在一起，以实现高速信号处理功能，这些功能可能以光纤通信的线路速率运行。信息可以被编码在光波的振幅、相位、波长、偏振和空间特征中，以实现高容量传输。我们重新审视了关键使能技术的进展，这些技术导致了最近的研究，在一个或多个这些维度编码的数字信号的光信号处理。各种光学非线性和色散已经被证明能够实现关键子系统应用，例如波长转换、多播、复用、解复用和可调谐光学延迟。我们回顾了在均衡，再生，灵活的信号产生和光控制信息（光学逻辑和相关）领域的高速光信号处理应用的最新进展。
Optical signal processing brings together various fields of optics and signal processing-namely, nonlinear devices and processes, analog and digital signals, and advanced data modulation formats-to achieve high-speed signal processing functions that can potentially operate at the line rate of fiber optic communications. Information can be encoded in amplitude, phase, wavelength, polarization and spatial features of an optical wave to achieve high-capacity transmission. We revisit advances in the key enabling technologies that led to recent research in optical signal processing for digital signals that are encoded in one or more of these dimensions. Various optical nonlinearities and chromatic dispersion have been shown to enable key sub-system applications such as wavelength conversion, multicasting, multiplexing, demultiplexing, and tunable optical delays. We review recent advances in high-speed optical signal processing applications in the areas of equalization, regeneration, flexible signal generation, and optical control information (optical logic and correlation).
