Title:
光信号処理装置
Document Type and Number:
Japanese Patent JP7110822
Kind Code:
B2
Abstract:
Provided is an optical signal processing device capable of improving computing accuracy without increasing the number of nodes of a reservoir layer. An optical signal processing device for converting an input one-dimensional signal to an optical signal and performing signal processing includes an input unit configured to perform linear processing on the input one-dimensional signal to convert the one-dimensional 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, an output unit connected to an output of the reservoir unit and configured to convert the optical signal to an electrical signal, perform linear processing to output a one-dimensional output, and a determination unit configured to determine whether the one-dimensional output from the output unit is to be output or to be input as the one-dimensional signal to the input unit.
