Abstract
An optical signal processing device capable of performing computation without changing a device configuration even when the number of input and output dimensions changes is provided. An optical signal processing device for converting an input M (M is an integer equal to or greater than 2)-dimensional input signal to an optical signal to perform signal processing includes an input unit configured to convert the input M-dimensional input signal to a one-dimensional input signal, and perform linear processing on the one-dimensional input signal to convert the one-dimensional input signal to an optical signal, a reservoir unit connected to an output of the input unit and configured to perform linear processing and nonlinear processing on the optical signal, and an output unit connected to an output of the reservoir unit and configured to convert the optical signal to an electrical signal to perform linear processing, and output an N-dimensional output.
