Optical Computing Machine - A simplified explanation of the abstract

This abstract first appeared for US patent application 18250378 titled 'Optical Computing Machine

Simplified Explanation

The present invention is an optical computer designed to have high scalability and reduce noise. It consists of three main layers: an input layer, a reservoir layer, and an output layer.

  • The input layer accepts an input signal as a computer.
  • The reservoir layer responds to the signal input from the input layer.
  • The reservoir layer uses degenerate optical parametric oscillator (DOPO) pulses generated by an optical phase-sensitive amplifier (PSA) as nodes.
  • The connection relation between the nodes is determined using a measurement feedback method or an equivalent method.
  • The output layer generates an output signal based on the responses of the DOPO pulses to the input signal from the reservoir layer.

Potential applications of this technology:

  • High-performance computing: The optical computer's high scalability and reduced noise make it suitable for complex computational tasks.
  • Data processing: The ability to handle large amounts of data quickly and efficiently can benefit applications such as data analytics and machine learning.
  • Communication systems: The optical computer's noise reduction capabilities can enhance the performance of optical communication systems.

Problems solved by this technology:

  • Scalability: The optical computer offers high scalability, allowing for increased computational power as needed.
  • Noise reduction: By utilizing degenerate optical parametric oscillator pulses and measurement feedback methods, the optical computer effectively reduces noise in its operations.

Benefits of this technology:

  • Improved performance: The optical computer's high scalability and noise reduction contribute to enhanced computational performance.
  • Faster data processing: The ability to handle large amounts of data and reduce noise allows for faster data processing and analysis.
  • Energy efficiency: Optical computing can potentially offer energy-efficient solutions compared to traditional electronic computing methods.


Original Abstract Submitted

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 including: an input layer which accepts an input signal as a computer; a reservoir layer which responds to a signal input 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 which outputs an output signal based on the respective responses of the plurality of DOPO pulses to the input signal from the reservoir layer.
