Title:
OPTICAL COMPUTER
Document Type and Number:
WIPO Patent Application WO/2022/091382
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an optical computer having high scalability and capable of reducing noise. This optical computer is characterized by comprising: an input layer (101) which accepts an input signal as a computer: a reservoir layer (100) which responds to a signal inputted from the input layer, and in which using a plurality of degenerate optical parametric oscillator (DOPO) pulses of a DOPO that are generated by an optical phase-sensitive amplifier (PSA) based on pump light as nodes, a connection relation between the nodes is determined by a measurement feedback method or a method equivalent to the measurement feedback method; and an output layer (102) which outputs an output signal based on the respective responses of the plurality of DOPO pulses to the input signal from the reservoir layer.
