Abstract

Classical signal processing functions such as spectrum analysis, correlation, convolution, filtering, mixing, and noise reduction can be performed optically using optical signal processing devices and systems. The signal media, i.e., light waves, not only have a higher information-carrying capacity than electrical wires, but may pass through each other without interference, thus providing an increased interconnection capacity. This property facilitates improved communication and ease of reconfiguration between processing elements in highly parallel optical computing architectures.¹
