Title:
OPTICAL SIGNAL PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/170872
Kind Code:
A1
Abstract:
Provided is an optical signal processing device whereby operational precision can be enhanced without increasing the number of nodes in a reservoir layer. The present invention provides an optical signal processing device for converting an inputted one-dimensional signal to an optical signal and performing signal processing, the optical signal processing device being provided with: an input unit for performing linear processing by the inputted one-dimensional signal and converting to a multi-wavelength optical signal; a reservoir unit for performing linear processing and nonlinear processing of the optical signal, the reservoir unit being connected to the output of the input unit; and an output unit for converting the optical signal to an electrical signal, performing linear processing, and outputting a one-dimensional output, the output unit being connected to the output of the reservoir unit.
